Common Procomp crosswind intake manifold problem.

These are standard heads on a standard block. The heads have not been angle milled in any way. This is a manifold issue. Opening up the mounting holes will not fix this problem. It's also the boss on the manifold where the head of the bolt seats, that is on the incorrect angle. I wonder how many 1000's of these inakes are out there with this issue.
I think since day one of production, they have had this fault and it's never been fixed.
