after pulling the heads of the 348 we noticed that the water holes on the deck were much larger than the ones on the felpro gaskets. any one ever port/drill out the gasket to match the diameter of the deck holes? any cooling improvements? thank you.
yes the runner have been siamesed to allow more air per runner, pretty cool looking heads you got there they sure to lots of hours to get them like that
