Auto X,
nice post. See those are meaningful numbers. Ima guessing those pistons are dished with a quenchpad?

My topend is very similar to yours.

20cc dish Icon pistons Scat sells with their stroker kits.

And looking back at my numbers the Edelbrock "63 cc" heads are actually 65 cc. Looked back at a post that MRL Engines confirmed/found the same thing.
