need help ASAP re vtec heads

Hey guys. Just found someone who is willing to sell a B16A VTEC head and a B18C VTEC head. For my B18A1, I’m thinking the B18C, right? Only logical. Just wanted your opinion since more ppl are doing the B16 VTEC thing. How much easier/harder is it to do the B18C VTEC? :shock:

Intake manifold is harder to fit and make work. I think more people do B16 b/c there are more of them around, so they are cheaper. If you search, you could probably find info on cam differences, etc.
