496 stroker stealth heads

This might help.
I will give % of differant heads I have on cars I have now running.

The % will be against the SR heads at.625 lift
These heads were ported to 750 lift by Comp-U-Flow.

Well ported 452 with 2.14 int and 1.88 ex.
Int 72% Ex 73%
These are on the 74 Duster low comp engine.Runs 12.20's

Ported Eldelbrocks
Int 90% Ex 93%
These are on a well built 440 and ran a 10.71 et.

Stage 6
Clean up only
Int 79.5% Ex 92%
I put these on the 74 Duster from above and no other changes and went 11.70's
These heads are defanately working better than the 452's.

Pick the head that you are going use on this build.
A lot of people buy parts thinking about there next build,buy for this build.
I don't know if any of this is worth anything or not,but I put it out there for you to think about.
All the flow bench work was done on the same machine.
