CrVtec

I read alot about the mating of a b20b block and a vtec head, the thing i dont understand is the valves clearance, what would I have to do to fix this problem so that i can change the cam timing? Aftermarket pistons? Also where could I buy a b16 head, a b20b/z block, and a gsr transmission? Any websites I can go to? Yes I have searched, but didnt find any sites, does hmotorsonline sell shortblocks, trannys, and heads?
