I know this has been talked about in the past, wanted to get some current opinions. Im running CTR pistons with JUN3s, do I have to worry about clearance with either the mugen or spoon gasket? Or should I be ok with either. I think my head and block have been machined but not very much.

 

you *should* be fine, but you really should find out how much material has been removed.

 

ok, so assuming my head and block were NOT machined, it shouldnt be a problem then. I guess I could always try that clay/playdoh method to check clearance, whatever the technical term is called. Thx
