Mopar bolt Identification assistance needed

While in the process of degreasing and cataloging my assorted 440 engine bolts, I've noticed different head markings.
I found a chart on B bodies only that has some information, but it doesn't go into detail. I'm interested in the years the particular markings are associated with.
In my case I'll be using a '77 440 block with '67 915 heads in a '67 Barracuda. I know it's a mismatch of parts, but I plan on building the car to look like it came that way from the factory with period correct mods.
I've got a full set of main bolts with the "H" style mark, another set with "TR". For the long head bolts I have 9 with the "H" and 8 with the grade marks. That's all I have cleaned so far. If I don't have a full set of the same external engine bolts, I'll post what I need and see if I can either buy or trade for the ones I need.
Thanks for looking.
