gsr has higher compression but is a better head to resist detonation
b16has lower compressionThe question you SHOULD ask is, should you get a GSR or B16 head? Tough question. Here's the deal...B16 heads share the same bolt pattern as ITR's for the intake manifold. They are easier to find aftermarket intake manifolds for than GSR heads. However, GSR heads have a distinct advantage over B16/ITR heads. Although it has slightly smaller combustion chambers that raise compression is an advantage, it is the reason why it raises compression, that is the REAL advantage. You see, GSR heads employ small flat surfaces on the edges of the combustion chamber called "quench" pads. This does raise compression, but the real advantage is this design's ability to ward off detonation. So, in my opinion, I would look for a GSR head not for the higher compression it will give you, but for the ability to run higher compression with it, safely.

read that link i gave you. it basically says that the type r isn't worth it because of how expensive they arewhat about a type r head? sorry im kidna of a noob but would that be the same as the gsr
