compression or flow?

Your dynamic compression ratio will be lower than your static 10.6 with your hot cam due to valve overlap. I belive believe wallace racing calculators has a dynamic compression ratio calculator that you figure in your cam specs.

I’d take compression over flow. Compression is key for hp especially at the higher rpm’s. The raw edelbrock heads won’t flow all that much less and are more forgiving at a higher ratio.

If I used the w2’s, I’d buy pistons to match.
