b16a block with b18c head? if it can, what modifications need to be made? is there anything wrong with this setup?

 

why would you want to do that? It's been proven that b16 head flows much better than the GSR head.... thats why people normally swap b16 heads on b18 bottom ends... or... do what you want and yes of course it can be done, but you would prolly lose horse power

 

well, actually, my gsr bottom end is messed up, and i just want an inexpensive short block to take its place.
