I have the good intake already for my app to clear a good p-7100. and I found out when I took the front cover to have it cleaned that it is a steel front cover. so it will be painted also. As far as cams go, im going to wait get the thing running and mounted. mold the cab around it and while its out for paint the engine will have a cam installed, compounds S4/HT4B, Billet rockers, chromoly push rods, valve springs, mild porting, stainless .093 lines, and some other stuff like that, I think I have the tappet I herd they didnt go to roller intill 91 ?
