Machined head.....
I want to install machined head (150 PSI,done by protec) on my gpr1200, and my question is - how many layers of head gastket to use 1, 2 or all 3. Any other ideas, any help appreciated, Thanks

2 or 3.... with a machined head, I think you should stick with the full gasket for a measure of safety. I'd stick with the full 3 layers.
