Hello Everyone,

I figured out after the fact that I installed large port (fiber) intake manifold gaskets on my small port engine - functionally will this work OK or do I need to tear it back down? Thanks Joe

If they seal up good, you are fine.

 

I swapped them out. It looks like it seals OK but the LH gasket is not restricted by the EGR port like it should be. I think in the large port applications this port is used for cooling water instead of exhaust/EGR.
