gasket question

[spaz416]

yea so this winter i am gunna be rebuilding my ex's top end with cam, valve springs, and high compression piston. i have been reading for a while that in order to get the advertised compression ratios for 400ex's you have to use xr 400 gaskets. so my question is what piston would you guys recommend and where to get it AND could i just order a complete xr 400 top end gasket kit and use that?

For the piston, get a JE. the bore is up to you and if you want ot run pump gas stay at or below 11:1. for the gaskets get teh cometic flexsteel gaskets. they are thinner than stock and are much less likely to blow. you can get all this from C&D or from your local shop
