The heads should work fine unless thier 425 nontoro heads in which case theyd have the odd lifter bamk angle and in 65 they only had the 400/425 the casting letters you'll have to look at when you have them and if you have an extra set of heads let me know I'll take a set off your hands

All 1965 big block Olds heads were the "A" casting heads. These are one-year-only and use 3/8" rocker studs instead of the normal 5/16" bolts. This makes the stock rockers oddball but also makes it easy to install roller rockers.
