Ive heard from a few people that the B16 head is a better head than the GSR head. All they said to me is that it flows better, so I guess my question is will a B16 head make more power on a GSR short block than the GSR head will?

 

It will make less power... lower compression.

 

What will make less power the B16 head or the GSR?

 

B16 head on stock GSR shortblock - less power.

B16 head on raised compression GSR shortblock - Type-R.
