I've studied TomJ's terrific website Ramblerlore.com and see he used studs & nuts instead of the OEM bolts. It's very slick! But rebuilding on the cheaper side as I'm doing is going to mean foregoing the hardware.
What about a middle kind of solution to replacing my 63 year old bolts, by getting say grade 5 matching bolts at my better hardware store? Has anyone done this?

My 390 came with one head bolt substituted with a hardware store grade 8 bolt. I was unconvinced, so I tried torquing it to spec and, you guessed it, it snapped. I bought a set of ARP bolts. I realize you are on a budget, but I don't think scrimping on head bolts is wise.

You’re better off re-using your 63 year-old OEM head bolts that were made in the good ol’ USA than use new Chinese grade 5 or 8 bolts bought at homer de pot.

If you're willing to spend some bank I'd go to Mcmaster-Carr and get some nice bolts if I didn't get some ARP stuff.

I ended up buying replacements bolts from a seller on ebay who removed them from a car in his wrecking yard, obtaining a suitable aftermarket replacement proved problematic.

Good show - I had no problem re-using the factory OEM head bolts in my 343 V8 rebuild. Old OEM stuff is made to standards quite different than hardware store fasteners of today and the only modern equivalents would be fasteners used for the aircraft and automotive industries (not aftermarket, with the exception of ARP).

I went ahead and ordered the studs. Figured I can afford 'em and with all the work (and $$) I'm putting in to the project, might as well do it the best I can. The more attention to detail & careful reconstruction, the more confidence I'll have driving her around.
