are they even compatible? wouldn't you have to get custom rods and stuff for that? I would advise against it just for the PITA factor..I mean you wouldn't be raising your compression any more than .5 or so..if you are gonna build for high horsepower then do it right the FIRST TIME. Don't buy stock internals designed for stock HP numbers..SRP makes 3 sets of 10.5:1 pistons (depending if you want to bore it over or not) for the D16Z6.
--You said head swap..what block are you swapping onto?
