B18c1 head on B16a block is it possible?
I own a 96 integra LS and I purchased a GS-R head about 8 months ago planning on doing an LS/Vtec swap. Little did I know how much money I needed to spend to finish the swap considering my car is an automatic. I know i know dont knock me for it, it is a first car. I was very uneducated at the time and I guess I still am. But anyways i am in the process of selling my integra and looking to buy a 96 civic hatchback thats near my house with a B16a swap already done to it. The question that I have is would it be worth the time and the money to port and polish the head, get a new valvetrain and get a new set of cams,then put the GS-R head on the b16 or should I just build up the b16? I really have nothing to do with the head i mean its just sitting in my garage and i want to put it to some use. Also what problems would arise if i actually went ahead and did the swap? Thanks

Yes, it is possible to bolt up your GSR/P72 head onto a B16A block. Its a direct bolt on precedure. GSR & B16A heads are interchangeable between B16 & B18C engines. If you plan to do this, it's suggested to run a Skunk2 intake manifold on the GSR head. The GSR head will give you little more low end torque & compression over the B16A head too.
Its up to you on which head you'd like to perform upgrades to, but just remember that you'll want to purchase a Skunk2 intake manifold (about $220-350 alone) for the GSR head, because reusing the GSR intake manifold can be problamatic (it will sit 7mm lower than it would on a GSR engine, colliding with coolant lines and other things on the backside of the B16A engine).
Come to realize it, it's more cost effective if you stick with the B16A head, and sell the GSR head and use the $$ towards upgrading the B16A engine. (Type-R cams, convert to OBD1 spec + ecu, have the ecu reprogrammed, etc)
