TRICKFLOW 325cc C.N.C HEADS

There are several builds that have been done with the TFS Streets that are over 800hp. A good well thought out combo would do it easily with plenty of room to spare. Start another thread with some info on your goals and there will be people more than willing to help. When questions like this are hidden in other threads, they usually get overlooked.

that's OK thanks
On the Ford racing super cobra jet heads. There a good budget head for $1800. For the pair. But they flow only 330/225 the o oh 325 TF 325 are $2800 and flow better

Then I look below the 325 heads to see the A460 340 CC heads not ported. UT assembled would they out flow the cnc 325's out the box? There.not much.more

Even the A460 cnc machined.race.heads 340 &360 CC cnc.heads.from 1430.00 to.1940.00 bucks

Well I thought we were talking about stock architecture heads. The A460's def want a bigger bore, use different intake's, pistons, exhaust manifolds, pushrods etc etc. But yes they will out flow most of the street heads out of the box.

" yes i am looking for stock head choice " block is just stock + 0,030 with self ported dove,s, 800 d/p holley, comp 280 cam, port o sonic, msd, 2 speed glide, 4.56 9"rear, 31 m/t,s was only wanting to know if the tfs 325 would have been a good choice over the scj as its hard to find a good porter in scotland & wouldn,t have to port the tfs. was hoping to reach my goal ove about 600+ before gas with a mafia intake, 1050 dominator, voodoo solid roller cam & roller rocker,s thank,s jonny

do they have cnc ones too.
wonder what the prices are non cnc
and ported and there flow #'s
thanks form helping out.I.got a lot to learn

P-51 heads are already somewhat CNC'd as the chambers and the bowls all the way around the short turn radius are delivered that way.

has delivered what do these P51'S Flow out the box with just a. 030 overbore.?
thanks how much are they and do the have standard Ford exhast pattern? Rasied exhast port and uses stick type intake. Did you get them completely assembled ?
Thanks sorry for all the?'s

I like really the price on the summit SCJ Heads for 1800.00. They flow 330/ ***. I to make a new post.
thanks

So you thin the p51Head out the box as better than the out of the box TF 325 Cnc heads out the box.
on a budget build? This is cost is going to be expensive I might have to sacrifice some power to lower my cost. Not trying to break any records. I once or twice sort of thing. Just want to run 10.00 all motor ' faster I wouldn't mind's then with my 250 plate system hopefully I can hit the 8.** mark then let sink in.

I know big HP gains come from the TF 360's with BBC exhast ports. But what I don't under stand in what headers to fir in my fox body?
Are you going 4.300/4.500 Stroke. And what compression you running?
What bore size?

go with 4.500 stroke,60 over on stock block, 325c&c tfs with about 14.5 compression (call ross and get pistons they have a camber mold of the head i made and sent in)the head has a 80cc combustion chamber , ,solid roller . call bullet and talk to Tim , he's sharp as nails , you will make the power your looking for
