I saw the one they had at Barrett. Who makes the aluminum heads for these?. Edelbrock no longer shows the rectangular port aluminum heads in their catalog.

I believe the heads are a spread port designed by Chevy for this engine.

Should be a quick combo for example my A/H Hemi the NHRA has us at 505 and we weigh 3200

Well, that`s a relief! I thought maybe this was the reason that NHRA brought in the SS/QA class, in case Chevy was able to convince NHRA that the 632 should be rated at 180 HP!
