Thank you everyone for you posts. Yes Mike, big block. Just kicking ideas around for both me and Dad...if prices are right and timing...
Might as well post the ootb numbers too......
I had the CNC Speedmaster knockoffs. They need offset rockers .630.
Thanks, I did t know that.Only the Victor copy needs the offset rockers.
The Stealth head with only the seats recut, valves back cut, and some bowl work, ends up in the 280/[email protected] range.
They’re generally in the high-250’s/low-260’s ootb.
After rework, they will easily support solidly over 500hp on the right combo.
A stock 452 is usually in the 220’s.
Plus the typical untouched 452 chamber is 88-90cc, the stealths are 80-81...... and closed chamber.
Unless you can get machine shop work done pretty cheap, if you’re going to start with an original set of high mileage oe heads....... you’ll probably spend about the same $$ refurbishing the old heads as buying stealths.
I haven’t seen the RPM copy style head available from SM in a while.
The only BB head I’ve seen from them for over a year is the Victor style head.
Between the SM & Edelbrock heads, which would you rather start with on a street strip type of build?A stock 452 is usually in the 220’s.

I was at the engine shop today and the owner showed me a set of Chinese knock off heads that just came in on a fairly new build. The owner went with all cheap Chinese parts in the engine and it was trash after a few thousand miles. The valves were mushroomed on both ends and the valve guides were loose. The guy saved a few hundred bucks first time around and now he has to do another rebuild and buy new parts. Chinese parts are junk. Buyer beware.
