There is a good chance that my head is warped, and if it is, then I might need a new head, and I found a good b16 head for cheap, I was just wondering what I will need to buy? Or will all of the b18c stuff swap right over.

 

for the most part everything will swap over but you will need a b16a intake manifold

 

So the header, distributor, and all that stuff will bolt right up then? How about the head studs, should I buy ARP ones, and if I did are they the same or are the b16 and b18 ones different, just wondering if I should buy them now or wait until I know the problem for sure...

 

for the head studs the b16 are to short make sure u buy ones for a gsr, but this set up works perfectly fine

 

Also keep in mind that a B16 head on your C1 block will result in a lower compression ratio than the C1 head yielded.
