So I tore the topend off of the blaster and i need a 72.5 piston which im gonna oreder here real soon.My base gasket is junk and im going to replace it but i have copper head gasket ,do i need to change it or i can reuse it?? And where is the best deal for a 72.5 piston??Thanks
 
sometimes you can reuse them if you heat them with a torch. you will be able to see the ring in the middle of the gasket raise if it is reusable. if not order an oem base gasket. and big bore head gasket
 
72.5mm is a big bore piston. Do you have pictures of your setup?

You can anneal the headgasket and reuse it or you can replace it. If it has any damage (nicks from removal or was bent) you'll need to replace it. Otherwise, anneal it and slap it back on there.
 
i would replace both gaskets for the piece of mind, and the few dollars they cost
not sure on piston pricing, i don't play bbk
