Well as for myself i have had the best results with A C C86's and as for gap .025 . I use that plug in ALL the I H gas engines next in line would be the autolite / Motor craft in the same heat range . I use /used them in my own 706 gasser the 460 gas and my S/H and the S/MTA and all my customers gassers

Autolite 3116s, I'll probably start going with ACs though as the last 2 boxes of autolite have had a bad one
