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.

Hylomar jointing compound spray on, shake well first lol this stuff always stays wet/gel, doesn't dry/tack like Copper
You can get it from Dakota Parts Warehouse, Brian Benson 605-388-3396 tell him Al from AK Racing sent you. Great guy to deal with

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.
