Jack, i'm having trouble getting pictures on this forum anyway here's a little info on the heads.
the only numbers I find on them is 101/5 this is cast in the rocker area.
they have 2 studs and 1 long manifold bolt. also oval intake ports.
no triangle wedges cast into the rocker area.
sparkplug holes have helicoils.
they have brass intake seats.
the valve spring pockets have shims and the new springs fit as they should they are the same OD as the 2 piece springs.
the retainers I have are steel and are of the flat design 2 of them have been ground in the center to make the small center spring fit the retainer and are a different retainer flat style
