I went with the stealth heads. Price was more in line with my Budget. They look good and just make sure to go through them And check guides etc..

The Pro Comps are Edelbrock knock off's. Good castings and everything I have seen looks to be real good.
Good Luck
I've been waiting to see the smallblock heads they were supposedly going to make...

I am wanting to build a quench motor that will produce about 500 horsepower for street use. The car is a 68 Coronet R/T and has all the torque boxes of a hemi car plus the Dana 60 Suregrip with 3:54 gears, 18 spline 4 speed, transmission. I have an Edlebrock RPM dual plane intake, a Holley 870 Street Avenger carburetor. Standard stroke crank, stock rods (all sized and rotating assembly balanced), .040 bore with TRW flat top 10:1 pistons, Felpro .039 Head Gasket. I have a new set of CAT 1.6 aluminum roller rockers and shafts that have been in the box for a few years now but would need to change them out for offset rockers if I go with the Engine Works or Procomp heads.
Plan to run headers with 1 7/8" primaries into 2 1/2" exhaust pipes and turbo mufflers.
I have not selected a camshaft as yet either.
Other new parts on hand: Ferrea SS Valves 2.14/1.81 Viton Valve seals OEM style "Hemi" Valve springs Keepers & locks but I can't remember what they are at the moment.

My machinist had a set of PCs at the shop.Said they were a total POS.I have Stealths on my 440.Fourthth year and no problems.I also changed to Comp spring,retainers,and keepers for the .588 solid cam.Machinist just relapped valves to satisfy his perfectionist ways and back cut them.Rocky

The procomp head is a ripoff of the Ebrock Victor head, a little overkill for this build.
Buy the Ebrock, RPM or the MP 452 or the stealths and lose those POS cat rockers anyway...

So I take it the CAT rockers have not proven themselves any good in the 5 years since I bought them? Hard to believe this project has been on hold that long.

Always buy overkill when it comes to heads. When the next build happens he wont have to buy twice.

Im Very happy with my Stealth head purchase. I like the fact that they look stock. I used them out of the box, just adding comp 10* locks and retainers, and the double springs that came with my Engle cam. My mild 451 street combo makes right around 500 HP with them.
The raised Port, Offset rocker design of the P-C's is more of a race head design than a street head. I'm sure they would work for you just fine also, although you are more likely to run into header fitment issues with an RB block and raised port heads in a stock chassis engine bay (???).
