360 issues-need help!

thank you for the help guys, maybe this weekend i will have the chance to check alot of the stuff mentioned and get this all figured out. i blew the collector gasket the other day, so that will get replaced too. is it possible that the 750 is too big for this engine combo? i have a stupid question concerning torque converters as well. the one i have in there currently is supposed to be a 2000 stall unit. the recommended converter for the Crane 302h cam is a 3000-3500 stall. how would this work with my current combination? would it really help to have this high of a stall? i drive this car around for fun and to work sometimes. hopefully i will be taking to the track for some fun next spring, but it will be a mainly street driven car for fun.
