Head gasket xr628

Hey all! for a 100mm piston on a xr 600 what head gasket do you use?

are the gaskets for the 650L the same thickness as stock? also is there any way to tell what kind of piston this is(manufacturer)? in the center it reads 3.00MM 4577P12 XH with an arrow pointing at the exhaust side

Thanks, nick

It's a Wiseco piston. Wiseco has the proper head gasket available, tell them the # stamped on the piston. Moose Racing and XRs Only have them too.

Thank you

I have used 650L head gaskets on my 628 XR'S almost exclusively. They are also cheaper than the 'BIG BORE' head gaskets.
