Part 2-B1 original heads.

I bought these heads from another racer that decided to go a different route. He never put them on an engine.
These heads have a lot of aluminum and extend past the block front and rear. Based on an old post by AlAlguire, I machined clearance on the heads for the rivets on Cometic MLS head gaskets. The block needed less clearancing, but I did that too. Just be sure to put the gaskets on the way you will use them. Since flipping the gasket over puts the rivets in a different location.

Attached is a picture showing the pushrod hole clearancing I mentioned in my next post for the rocker arms.
