To anyone still following this,
The HKS gasket is 79mm bore, the HKS piston is 77mm. I am thinking of re-using these or getting something similar made.
When getting the gasket made, should I go the 79mm bore on the gasket again, or go a bit tighter to the piston, say 78, or even 77?
I am pretty sure I am going to go with the 1.2mm thickness now.
Cheers, Andy
