they closed my last thread..

i just got a quick question. i got factory heads on my 77 360. 480 cam 292 duration, stock dished pistons, heads have been ported with new valves and alittle heavier springs. (i dont remember exact specs on heads for i built it along time ago in highschool at the speed shop). my question, since alum heads are just too far out of my price range right now, i got a set of good magnum heads for nothing. they came off a 99 360 magnum out of a 2500 pu. i can do all the machine/ assembly work myself. would there be any power gain in putting the magnums on my 360? and if so what all do i need to do the swap? i know about the intake and i think ill need different pushrods but im not real sure.

thanks.
