Is the 6-71 normal helix? Teflon'd? Will drive be a Gilmer belt?

Jack,
They are definitely ‘59 531395 heads. I think the rockers are Ford only markings on them are 7/16” 1.5. From a post I did a while ago in the race section it was believed that these studs are from Paul Spotts.
The rotors are helix not teflon stripped. The drive that came on it has 1/2” pitch 3” wide pulleys. I haven’t done a tooth count yet. Pictures of head and drive attached.
