The newer H.O. heads were preparred from the factory with roller springs and will kill your flat tappet cam lobes.

1985 and newer ford 5.0L engines were roller. As I stated above, you are not going to like the Summit camshaft kit with roller valve springs. Call me and let me know how many lobes get wiped out before you finally shut it down and pull the camshaft before you figure it out on your own. That camshaft kit won't work out for you on H.O. heads.

70's block with 1980 heads will be fine with the .471 lift cam from summit. I ran the dog crap outta mine for nearly two years before I sold the car.
