We ran them on the hemi , back in the day , w/ dick landy corrected rocker arms, they worked great , AND WERE ADVISED BY CHRYSLER/TOM HOOVER, FOR BIG CAMS/785 lift cam dynamics'' IN THE HEMI AT THAT TIME .
I TRIED THEM ON MY CURRANT 440/505 , AND IT THREW THE GEOMITRY OFF WAY BAD . Excuse the caps--------------
