ok, so im looking to trade my gsr head for a b16 head. my head is complete except the valve cover, i will send it if you want it. the head has aprox 170k on it, but its still in great shape. i recently pulled it off my old gsr, and i checked it out and everything is still in great shape. like i said im looking to trade for a b16 head. let me know if your interested. i will also include a brand new set of custom cams, 12.2 max lift, unsure of the duration, with the head if your interested and your head is in good shape. must be complete
