Are you talking about '87-later manifold on '86-earlier heads?

yea, drill, mill, something!.....the newer intakes have a different angle on the 4 center bolt holes.....don't know why GM did this, but the center holes are at a much steeper angle than the angle at the heads.

I'll be looking into this during the summer. I'm putting Brodix IK200's in my IROC so I'll hvae some machine work to do. I was thinking of maybe getting some washers and folding them slightly with a vice so that you can get maximum contact for a nice seal. I'll let you know what happens when I get to it.
