need help with heads..

[kennyhammond]

Ok I got a 90 chevy truck with a 350.. well pulled the motor because either the head gasket is bad or I ha ve a cracked head.... so for now I put a spare 305 in it to drive ....so I am left with the 350 to rebuild.... I am not wanting to spend much money if any at all...plan on making it just a little fun to drive but nothing wild...so my question is can I put the 305 heads back on and put my throttle body on it and be good and see some gains or ........ plan on a small cam change also. Any info would realy help plan to build next week
