Hi all,
I will be having my engine rebuilt with all the goodies and i have a question on CR.
What would be the average amount of material shaved off both the head and the block. 4 thou off each??
When the head and block gets shaved,so as the gasket can seal correctly,will my CR rise alot?
I have ordered CP pistons at 9.0:1 CR (stock RB25 CR) and a 1.2mm Cometic headgasket (stock thickness)
CHEERS
