Inliners International Forums General Discussion Engines 82 250 looking for info on heads?

ok here is my story i have a 82 c10 i bought with a 250 in it. i plan to swap it out for a 350 i am getting off my friend. and redo the truck. any way i want to use the 250 in my hot rod i plan on building. ony thing is that it has integrated intake manifold. well i wnat to do a individual throttle body set up so this head will not work. which would be a good head swap for doing a very heavy built motor. like can i use a 292 or 230. or stick with a 250 head. or do i need to find another engine all together? thanks for the info!!!
