A.P.D. does an Iron 460 Ford Head (2.250 valve)

Bravo to you,your work looks great. Have you did any A-Head stuff? and if so what were your results. Thanks for posting your work.

... thank you very much, it looked a lot better before we cooked the darn thing, lol ... i was in a hurry, and excited to see what i could get out of this head, but i got tired of all the junk/rust/crap/dead things in my hair !!! ... lol ...

... i have not worked with an "A" head ... yet ...

1. THAT IS SOME AWESOME WORK YOU HAVE PERFORMED!

2. If used in a "everyday" application what would the survivability be with good valves and seats in a non rollor motor application. For a good old low end torque, low compression truck style motor.

3. For some of the guys that caint get or afford D00E-R castings and have work done to them this could be a new avenue for us weekend warriors and possibly some bracket racing applications!

... thanks, but if you were wanting a ported head for an honest { good old low end torque, low compression truck style motor } ... then i would use a smaller valve, and a little different port shape, reduce my convergance point angle by a couple degrees, shrink my throat % up a bit, shrink the 2nd choke-point % up a bit, and use a little different shape on the short-turn, and use a different seat cutter with different back-angles on nthe valve to get the port to "turn-on" sooner, as you would most likely not have too much camshaft in an application like that ...

... i will be measuring the actual amount of guide-height of the as-cast port compared to the ported port, i will post that as soon as i get a chance, but as long as the geometry of the valvetrain is set correctly, the durability should be good ...

... well, looks like .340 was cut off the guide length, but it's no biggie, we will be installing 5/16 guides & valves in these heads and we'll get most of that back ...

... i also had some time to work on chamber and exhaust port some today, i just finished for the day and didn't have time to flow test it yet, i need to re-touch my valve job as the baking, shot peening did a number on them ( ) ...

... but i thought you guys might wanna see it anyway's ... ... also, we sonic checked the ports, and we have no "less" than .100 of material thickness after porting, so we are good on that front ...

Nice work. I think the PPC nickle bronze guide would give you plenty of support. Nice work.

Very nice work.

Those are some of the best numbers I have seen for a stock pass bbf head that's wasn't a dooe r. Nice work looks real good

a few questions..

these heads going back on the same engine? what size is the engine?

they were not ported for this pulling engine before you guys got them?

1. yes
2. 470c.i. limit
3. no

Do you have a pic of the intake port?

... sure do ... ... there are some on the first post in the thread ...

... well guys, i was working with the "D3VE" head today, and i spent some time on the chamber, intake port, but mostly on the exhaust ... here's where i'm at so far, and there is more in this intake port, i was playing around with some wings and diffusers, and some clay and i saw 406.7cfm @ .750 lift ( ) ... i have some epoxy curing tonight, so tommorrow we'll see what she'll do ...

(A.P.D. D3VE Head)
"Intake Port"

.100 - 76.6
.200 - 153.3
.300 - 228.7
.400 - 272.0
.500 - 326.2
.600 - 362.1
.700 - 382.0
.800 - 391.4
.900 - 401.8
.950 - 406.7

"Exhaust Port"

.100 - 69.7
.200 - 120.2
.300 - 157.3
.400 - 189.4
.450 - 193.6
.500 - 186.9
.600 - 184.3
.700 - 183.5
.800 - 183.8

... well, i spent some more time on the "D3VE-A2A" head today, and it looks like the floor/wing is almost there, we have some "Wings on a Stick" made of epoxy, and the port has a little bit more in it from what we saw with those, so i'll keep tinkerin' with it until i get it ...

(A.P.D. "D3VE-A2A")

.100 - 82.9
.200 - 159.7
.300 - 225.6

.900 - 408.9
.950 - 413.8


.... and for the latest on the exhaust port, well, let's just say its havin' its way with me right now, lol ...

You tried laying down the short turn on the exhaust?

dfree383 wrote:You tried laying down the short turn on the exhaust?

... a little so far, but that thing has a horrible turn to make, but i have not sonic-checked it yet in that spot, the rough cast is impossible to sonic test, but i did not want to break through right there, i'm not sure how close it is too water, so i just blended it smooth, ... but i'm sure it will need some more material taken from there ...

... man it's really a shame these heads have this exh. port, this thing would be a killer street/strip terror !!! ... the FPS on this thing is stupid !!! ... i mean it's no race head, but there are plenty of em' out there, heck we were at a core suppliers in Texas, (Nationals Week) and i've never seen more BBF iron heads in my life !!! ... they have pallets of them !!! ...

... we picked up a set of EFI "E3TE" heads, that is the cast number, i think ??? ...

... i went with a 2.150 valve in this one, as the wall thickness isn't as much as the other head, plus with the valves being past bore-center, i'm hoping it will respond to this size valve, and the exhaust port is much nicer, much much nicer actually ... i'll have that one on the bench tommorrow hopefully ...

Laying back the short tuns on the exhaust won't help your bench numbers, it seems to cause the flow to serperate and go turbulant.

any updates?

I wonder what this guy could do with a set of SCJs or P-51s or even A460 heads...... or even TFS power ports

... sorry i have not been around for a bit guys, we are very busy at the shop and we basically had to put our "Shop Projects" on hold for a bit, as we have been working with our new 5 axis CNC machine, and getting all the bugs worked out, which she is workin' wonderfully !!! ...

... we have been cutting heads and they have turned out super nice, and the locations are spot on, so we are in good shape with that, but now we are working on getting our "Fixture Plate" inventory up to snuff, and the BBF is in the works, this tooling stuff is really exspensive, WOW !!! ...

... here is a shot of a canted valve Pontiac head, believe it or not, but it is based on a Yates C3 Ford Nascar head on the intake side anyways, so its kinda' Ford stuff, Right ??? ...

I was kind of wondering what you could get from the heads I mentioned...... maybe someday soon you will have the chance....

... sorry, i did leave that part out didn't i ?? ...

... but hell yes, i love porting heads and developing new shapes, and the canted valve stuff seems to keep my interest the most, the port in the pic i just posted is a 291cc runner, with a 2.125 vlave, and on a 4.155 bore in went 414cfm !!! ...

... but to answer your question, if anyone here has a head of any of the types listed by the Coug, or a head you guys feel would fill a need for a CNC package, please feel free to contact me at the shop ...

... i have no doubt i could make one of the heads you listed Coug rock, i just need some castings to work with and get the shape worked out, who ever supplys a work piece for me at the shop, to develop a CNC program for, i will give that person a nice discount off the "First" set we CNC for that head, hows that ?? ...

... and it does not need to be a new casting either, even if two of the chambers are melted out from a N20 combo, it dont matter, as long as i have one good cylinder to work with ...

... and i will disclose full detail of that port shape and its specifications, and pics for viewing on this forum ... and i can tell you this, our prices are very hard to beat as well, we aim to compete with this CNC machine !!! ...

... any ideas ??? ...

I may just have to call you I am on nights now, may have to talk about this.... check your pms
