The heads flow pretty much the same.
There are very few differences when matched up on a flow chart.

The GSR head will drop a B16's compression .2, the other will raise .2, It is a useless swap, unless you want to boost the B16 w/ GSR head, then I suppose it's not completly useless.

However, .2 is meeger when relating to boost.

 

the gs-r head on b16 will raise the comp .2 not lower it. it lowers it when you put the b16 head on c1 block. i thought we went through this already jeff. remember the thread? charles had to get the "white paper" on it. remember the b16 head flows 5.25% more than the gs-r. so that means that it would drop comp because of the quench area being bigger. a bigger combustion chamber will lower compression.
