I'm switching out blocks on my B18C1 so my head has to go to the shop.

Putting in ITR cams, and a Mugen 2-layer thin headgasket. That is said to raise compression, what, .3 points?

Im going for a high compression re-build, w/o having to upgrade fuel managment at the moment. How much can i mill off the head to get safely into the mid-high 11's in compression?

I just dont want my pistons slapping my valves.

 

 

I would just resurface the head if your already getting a thinner gasket. Get some P30s in there and with the gasket you should be around 11.5 to 12s

That's the thing, at the moment i do not want to do pistons. So, milling the head seems like the best choice.
