Look what came in the mail yesterday.
Procomp BB head, the one I paid $120 for off ebay.
I'm gonna have some fun with this one.


Spark plug boss is sticking way out into the chamber with super sharp edges.



Sure looks pretty.



Very sharp short side turns both intake and exhaust.



At least they barely touched the runners with a carbide and didn't touch the bowls at all. Make it easier to blend for the DIYer.




Last one.
