How do I get the highest compression ratio for LS/VTEC...........

Ok, I'm mating a GSR head on a stock B18b. What and who makes a head gasket that will get me into 10.5-up compression ratio?

a head-gasket isnt going to yeild the "highest compression" ratio you have in your title. U want high comp you have to get high comp pistons.

I'd like to add that you may have to run 92 octane on this because the higher compression is going to change the 'explosion' properties. Also, you may want a tunable ECU.

If you wanted, with a set of high compression pistions and the proper head gasket you could get your compression close to aroud 12.7:1 to 13.0:1. Though if your going to do this, you need fuel management, and a completely different valve train to make good hp, amongts other things.

I am looking for other alternatives as oppose to changing pistons or milling the head since this is a really really really budget buildup. If i had a chance to do it the right way i would go with b16 pistons forged rods etc etc . Since all I really have is the head and ecu i wanted to see what I can work with to bumo up compression a lil more.
