Hi community
In the intake manifold gaskets from the OMC king cobra 454 there are 2 removable metal closing caps to close the exhaust channels which goes through the heads. Now I have 2 different versions. One is with a small hole and one is fully closed. Which one should be used?
Or leave them completely out of the gasket?
What are these plates good for? Can it cause heating of the intake manifold without it?
Thanks Noldi
