2 weeks ago in this "engine tech" section there was a thread started with quite a few hits, look back a few pages or search for keywords cnc pro-comps...

Quick summary for you:

-Out of the box they are no better than a mildly ported set of factory passenger car heads (D0VE's, D3VE's). W/ some more effort into the porting and some bigger valves the passenger car heads will greatly out flow, and out power the out of the box Procomps. Max effort porting on both and their close to the same.

-They are best bought bare because the included hardware is iffy and the valve seats on them are pretty shoddy.

-They are more or less equivelent to aluminum passenger car heads and are no way in the same league as the other aluminum BBF heads out there.

That being said, for a moderate build (not a racing application) they can be a decent head that will shave some weight off and perform well for a street car.

Seriously though, if you do a search for "procomp heads" you will find weeks worth of reading Once you dig through all of the bickering you will find pretty much what I've summed up here.

Two things are infinite: the universe and human stupidity; and I'm not sure about the universe. -Albert Einstein-

Probably a better choice, it all depends on what you want this combination to do. I just bought a set (PRO-COMPS) for my 472, kind of anxious to see just what they will do.

If you're not living on the edge you're taking up too much space!

All im really looking for is a fun street car that is diffrent.400-450hp,And maybe a little fun juice. I found this 1987 mustang convert 4 banger, In mint condition this old man was selling, So i figured its a good starting point for something like this.

The short answer is that the iron heads you already have will make equal or _more_ hp.

Long answer is that if you're going to spend a dollar on junk Pro-Comps, save the dollar and spend it later on heads that are a real upgrade over stock.
You need to do at least some light porting on the stock heads, the exhaust as cast is nasty. This shop

ports heads, or for cheap they have instructions with photos on how to DIY. No I don't work there ;-)

Forget what you see in Car Craft etc - the articles are 97% written for the advertisers, not you. You can get 450 hp with no fancy parts, stock heads, pump gas and moderate rpm. Do it right rather than fast and you'll have a no-headache machine.

I have procomp's on my 460 Tbolt for 2 years now. No problems so far. I use my car for street use, and it runs very strong. My suggestion is to buy them bare, and than buy name brand valves and springs.

Judging by what you've conveyed here I will almost bet you have never actually had your hands on a pair of ProComps or tested them against one another on an identical engine; either on a dyno OR a race track. The iron heads won't equal the ProComp's performance unless you somewhat port them first. AND, then there is the matter of 75 pounds difference.
The ProComps have their place, especially on a street/cruising type vehicle; just NOT on a race car.

EDIT: Actual TESTING will and can put a lot of myths by the wayside...lol.

This what I did and have not had a problem.

Are they junk...NO Are they the best ....No Are they worth 750.00 bare for a pair I think so. JMO Im no pro but seems like what you are trying to acomplish there gonna work great, the less nose wieght the better in that fox chassie. But if you have plans on future stroker combo's and gonna upgrade I spend the money on better heads so theres room to grow. If I did it over I'd probly did the BT's or the P51's.

I've had several sets of the Pro Comps come through the shop mostly for small Ford engines and I think that the casting quality looked really nice. We dyno tested a set of their CHI knockoffs vs the real CHI 3V's and they were down about 30 horsepower on a 400 horsepower 355 Cleveland. I have a set on another Ford a 302 with a supercharger and that engine made 500 horsepower at 5500rpm so it runs fine.

As long as your goals are realistic the Pro Comp heads could be a bargain.

Guilty as charged. P-Comps have gotten so many bad reviews here I figured he could do better... but, er, I've never touched a set.
