Stock b20 Head Gasket on 85mm bore LS/VTEC?
I know the stock b20 bore is 84mm and my gasket actually measures 84.275mm. The question is will this play a role in the pistons smacking the hanging over gasket.
Before you say "yes" or "no", listen to the following.
GSR Head (still 81mm combustion chambers).
JE 11:1 pistons (dome on pistons is only 80.XXXmm wide to squeeze into combustion chamber) from 81mm to the edge of piston, it's flat. This portion of the piston never raises higher than deck level.
Will this be OK or should I have the gasket Machined the extra .035 (rad) to get the 85mm?
