Intriguing, I will be watching. The only things that come to mind are the rings, valve guides, PVC system. Head gasket?
Hmmm.

Thumbs up Sounds like you already know the cause,
VITON Seals with Bronze Guides are all I use and would highly recommend.






I too have never had or heard of Overheating issues with these Cammers.
Oil pressure issues were one of the biggest problems early on.

Do you know what the valve stem to guide clearance is set to for the intake and exhaust on your head? We are having a hard time finding the spec for that.
