i am planning on raising my CR with pistons n rings......
but the install will cost me a lot...

what about getting a spoon head gasket...bumpin my CR to 10.4:1....
almost itr spec...

im making low to mid 180s now with stock CR n TODA B's

 

I would do both the gasket and pistons.

But you can also mill the head to gain some compression also.

 

have you dyno'd the car?
