Excessive heat on an air cooled engine looks like. Also known as a blown head gasket lol. Id say too much compression mixed with not enough octane. Is that 2 different head gaskets also?

that is just one head gasket.

Your probably right about the compression being too high......165ish :smile: 110 octane race fuel.

I hope so....it was over 165 before.


Compression should be about 150 now

I'll test it out tomorrow.

Whats your squish going to be with that much more gasket? Im assuming youre at your max for port timing by raising the cylinder and the gasket is the only way to lower your compression at this point. double the head gasket and squish for certain is going to suffer.
