Previous owner of my SCJ heads had a big roller cam so I left the springs with him.The factory springs and hardware that comes on the "A" head will accommodate my cam (.655 lift and 125/325 lbs.) but I see the Ford replacement parts are not available.Who's pieces are guys using?

The flat tappet head had Crane springs #99893 however, many outlets have copies of that same spring.

Any info or part # on the retainer?Was it neutral,+,-?Same for keepers neutral,+,-?I can't find a detailed parts list for these heads.Trying to keep it simple and not over think this but don't want to under think it either.I was going to swap the stuff from my D3's to the SCJ's but I have a possible buyer for the D3's complete.Thanks again.

The moly-steel retainers were originally also Crane +60 and the spring cups were from Comp.
Locks were machined 7 degree but, I think a hardened stamped lock will do.
