4.37 is .120 bigger than 4.25 bore. .060 bigger than 4.31. That is .030 to .060 gap between bore and sealing ring. Wouldnt want to go any tighter.

Any issues with running 4.5” bore cometic Head gaskets on 4.5” bores? Pistons are down .010 in the hole and I don’t feel any lip into the bores. I see some advice here to go bigger than the bores and wondering if I have an issue here. |
