need to know which intake gasket to buy for trimming up for my intake and heads that have been port matched

 

SCE - measure your port dimensions and get a set that is slightly smaller to trim up. Put a light coat of 3M weatherstrip adheasive on the heads and the gasket(around ports and water) apply the gasket and clamp the manifold down, let it sit overnight, then remove the manifold and trim the gaskets with a razor. Then put some silicone around the water openings and china wall - torque the manifold down and you are done.

 

sounds like a plan,thanks
