Actually that's what I do. I help people work on their cars for a living. Enthusiast like yourself looking to get a little deeper into the car but not exactly sure how to go about. Like the pishta was saying if you just need a little valve lap and some new seals and maybe if you want a little extra fun on the cheap tossing in a cam while you're in there and some Springs while you have them apart? And again like the pishta was saying drop them off at a machine shop and let mill .050 off. For a very inexpensive rate I help people and guide them through the process. Here's a picture of a customer 68 El Camino that we hopped up the motor a little bit as the non knowing crowd likes to call it LOL cleaned up the engine bay. Of course not before completely restoring all the front end components. Safety First!
