Try putting oil around the intake manifold where it meets the head. If it gets sucked in, replace the gasket. I had a 69 Camaro that happened to. It had no get up and go but was like a work horse after I replaced the gasket. My neighbor gave that little trick to me. He took the oil can, squirted some oil on it, low and behold the oil disappeared in a couple of places. Vacuum leak found!
