I know I saw this somewhere but cannot find it. I have a 1972 455 all stock. I want to put aluminum intake on. What homes do I need to plug and what is best way to do that. Also a second option is I have rebuilt 1967 400 heads, and the aluminum intake combination I could use. If did that route, is there anything I need to do. I will keep the 72 lifter oiling system. Will compression be better with the 67 or 72 heads? I just want a daily driver for next few months before complete rebuild over the winter. Car is a 1978 century with 200 4r and 3.89 Ford 9 inch rear. Thanks for all your guidance.
