These don't appear to have any accessory mounts. I don't know if you need them on your engine. I can't guaranty that they will fit your car, but you could give Speedway a call. Their tech department may have experience fitting them to something similar to yours.
If he uses the stock heads he won't need them as the mounting holes are there. Early sbc heads did not have mounting holes which makes them a PITA to use. The main problem with many later castings is that they are thin wall and large combustion chambers for emission standards. I replaced the heads on the 350 in my 76 Vette with 624 castings even though they are prone to crack. From information I sourced the cracking mostly occurs with 2.02 valves and mine are 1.94's and so far I've had no problems and the Vette runs at a constant 200º.
