head comparison d0ve-c Vs. d00r-e

Just out of personal curiosity what is the difference between the two sets of heads? I know that the d0ve heads were for passenger cars and that the d00r-e heads were the cobra heads, but when placed side by side what benefits does one set have over the other if the rest of the combo is exactly the same?

On an as cast basis, the DOOE heads have a smaller combustion chamber 68cc +/- vs. the DOVE at 75cc +/-. The DOOE had larger valves as well as larger ports. When ported they both are fine heads for racing, but the DOOE will outflow the DOVE's by quite a margin. The DOOE's also came with adjustable rockers and guideplates.

Most cj heads I've owned have been about 72ish on the combustion chambers. Great stuff as far as factory iron goes, Blake has a set blowing over 400...... They may be old but they work !!

Even though i Like them, and i dont say this in a disrespectful way, the D0VE's are the "get by heads." People get by with D0VE's, till they can afford a more suitable head. They dont do really anything better than any other head, but they do work pretty well and they are reasonably cheap and plentiful.

On smaller engines 475ci and below, the DOVE's are superior unless it is an all out race engine. On my vac limited 552, I also don't think I would have seen any performance gain from a set of DOOE's either. I had a long thread on the other board where it was discussed at length by some very knowlegable people, and the concensus was the DOVE's would be a better choice in this specific application.

On a 552" motor you see a substantial gain in hp with cj heads over a set of doves IMO could be 75-100 hp difference.

It's a vacuum class motor. If it wasn't vac limited yes very likely a substatial gain. I am required to pull 17"@1000rpm. I have run against a guy who has the DOOE's on a 557 in that same class and I can beat him on an even track all day long.

My brother has been runing a set of doves and he is beating people with PI heads and cj heads in a vaccum class. The class has to pull 17" of vaccum at 900 rpm. I am going to them next year.

the question didn't specify specific classes or rules just side by side compairIson?

dfree is right I'm not looking at any specific classes or anything like that, just wanna stomp some bowtie and mopar butt with old school iron. Current build is looking something like this on paper:

1050 Dommy
Victor manifold (port matched to heads)
d0ve-c heads worked by my brother
429 bottom end w/ .030 over
comp cams kit K34-770-9
Forged flat top pistons

This will be backed by a t56 manual trany
and 3.50 gears in a 72 gran Torino

First things first, Ditch the 429 rotating assembly and either put a 460 or stroker assembly in it, Inches are power.

#2 Ditch the Dove'c if you have some CJ heads.........

#3 look at a Soild lifter cam if you looking to make power on a budget, hydraulic stuff is for getting grocerys, not racing.

Ive already got the d0ve heads, $100 for good builder cores seems like a pretty good deal to me. As for the cam, the kit number I listed should be for a mechanical roller. I dont recall the exact specs off the top of my head at the moment but the kit comes with just about everything I need for the valve train except for the rockers, valves and push rods.

FYI, his cam kit is:

Xtreme Energy Camshaft Kit Mech RollerRPM 2200-6200Adv.Dur. 274 Int./280 Exh.V.Lift .650 Int./.657 Exh.Lobe 110 DegIncl.CamLifterV.Sprng/Ret./Lock/SealTiming Set

My Bad I thought it was a 274EX Hydraulic......

IMO spend the money on better heads and a stroker kit, you 'll gain much much more from it, than the roller cam, 429"s and Iron Doves.

Aluminum SCJ are dirt cheap right now and the can be painted.......

At the moment I'm trying to keep the cost down on my build, like near the $4500 mark, If someone here happens to have a 460 crank they could send my way for not too much coin then I'd grab that up in a hurry as it would open up alot more choices for pistons. Aluminum SCJs would be really nice but they may have to wait for a second BBF build, something in the neighborhood of a 545 for my second build would probably be exactly what I need.
