I need to know if a B16 block with PCT pistons will work with a GSR P72 head? are there clearance issues?? I have a B18C block right now but the rings are kakka and im going back for another tour in Iraq soon so i dont really have a bunch of time to F with rebuilding it, so is a P72 head on a B16 block with PCT pistons going to b ok??? or is it not worth the hastle>??

 

I seen gsr head on b16 block before...i could imagine it being slow.

 

not much help but... you should so vice-versa. GSR/LS block and a B16 head
