Bigger Gaskets???
Pulled my plenum, runners, and fuel rail the other day and discovered that PO had attempted to port the runners and hacked up the intake manifold a bit as well. I think it can all be cleaned up just fine but I am looking for a source for some oversized gaskets that I can match to. I'm hoping that I can clean up the porting to match the larger openings in the gaskets. What would you all recommend for the gaskets?

Re: Bigger Gaskets???
Guess I should have asked for recommendations on the manifold to head gaskets as well. I have yet to pull the manifold but I'm assuming stock sized gaskets will be too small as well. Thanks.

Stock will most likely work, I like fel-pro 1204 or if bigger is needed 1205, 1206
