I'm running 73-?? 4wd headers on mine by Dynomax. My oil pan clearance using my stock crossmember was very close so I used a couple washers between the block and the engine mount to raise the motor up slightly. My bbc is a 1989 454 from a C30 so it has the truck oil pan.

I did have to grind a little off my passenger side frame rail to make the headers fit.
