Hello, I am looking at buying an L26 engine for my 240z the plan is to use the l24 flat top pistons and a decked e88 cylinder head to get more compression. The ozdat calculator says that with a 1.25mm thinner head gasket and the l24 pistons I will get a compression ratio of 10.5/1 is this equivelent to machining 1.25mm of the cylinder head and using the stock head gasket? Is it even possible to remove that much material?
