.20 overbore, stock headgasket?
When my motor was rebuilt they used JE 84mm pistons and bored the block over .20.. I have heard when you do this you also need a bigger headgasket, one to match the bore. MY shop just used a stock honda headgasket, and its sounds like the head gasket is slapping. Any suggestions??

If this is a B20 block and the used aa stock B20 gasket you're fine, but if this is a B16/B18A/B/C and was sleeved to 84mm bore then you would need a Cometic 84mm gasket or if you have an LS motor bored to 84mm then a stock B20 headgasket is fine even .020 over or .5mm over no probs.
