Compression is not a problem. Usually 516 heads in 67, but you never know till you check. Should have forged crank and good rods. Cam, intake, a good Carb, quick curve distributor. I'd add a high pressure spring and a windage tray if you are going to wind it up. Get as much info as you can from the previous owner including machine work and parts installed in the engine. Don't go too wild or you'll botch a sweet driving car.
