b18c head swap?

I just recently swapped a b18c head onto my 92 LS bottom but have a question. I have a skunk intake manifold but ran into a a little problem. Anyone who did this swap…was it easier to use the b18c throttle body or the LS? Also, coolant lines to the block and manifold…I am having problems hooking them back up-there is an extra one that hooked up to the LS manifold and not found on the b18c? Any suggestions…also searched…thanks!!!
