What you do is buy a cool head then get big bore domes for it. Call jeff at F.A.S.T. he's one of the site sponsors. And it uses rubber o-rings that are much better, yes. The can be re-used alot of the time and the are more durable and last longer

Remeasure that cylinder.

If it's a supercub, you can get a NOSS head made for the super cub.

If it's a stock cylinder...good luck.

 

I know at 68mm on a stock head there is paper thin material between the Oring groove and the head stud.

ON an aftermarket head, stock stud design, not a ton of room either between the dome and stud.

 

Make sure you do in fact have a 72mm piston, then give Dave Noss a call to help you out.

 

I got a feeling you're just gonna have to run your stock head with a copper gasket.

And if that's the case, get your stock head polished for the bling.

 

Have it smoothed over, nubs and fins taken off, and polished. They actually turn out pretty nice!
