1978 Cadillac SDV (Commodore Blue Met.)
Hello everyone! I finally finished up removing the center plenum area from my 472/500 intake manifold and have removed the stock single plane manifold from my 425. Im ready to make the swap now but first wanted to get some advice from anyone on here that has any experience with this. I have the felpro intake valley pan gasket. Ive watched many videos on youtube of this job but their r none that r done on a cadillac and it seems that peoples techniques vary quite a bit. For one, most people seem to toss out the 2 rubber seals for front n back of block n just run a nice fat bead of rtv instead. But most of these gasket jobs r also not the valley pan style either so should i use them or toss em n go with just rtv? Also do i need to trace the port holes on both sides of gasket with rtv? If anyone can help me out with a lil knowledge on how to successfully complete this task itd sure give me alot of piece of mind. Please help and thanks in advance!
