Advice on which heads to use. 360 , 302???

Yeah Moper.. Thats what I was leaning towards.. And yes there were shims.. So I guess I can gasket match the 302's for now and just let the 360 heads go.. I havent really bought the 3600 heads yet.. My buddy was just going to let me use them and see how I liked them.. But being open chamber, I was thinking it would be too much for the motor combo I have.. Thanks to all... But I guess I have made a decision to run with what I already have and not buy anything else for the time being... Thanks again to all who have chimed in with advice and I will post when it is completely installed and running!!!!!
