Hello all. I'm going to be replacing the intake manifold gasket on my old (93) Chevy pickup. It's the 350, and when you pop the hood, you can actually see the engine. It's the first "new" vehicle I ever bought. I bought it in 94, with about 10K miles on her. Anyways, long story short, I'm replacing the intake manifold gasket. External coolant leak. It looks like a fairly straight-forward task. I've done some looking on the web, and found a few "how-to" videos. Anyways, is there anything else I should do, or look at, while I have it torn down? I don't want to get too carried away. I'm thinking about putting new valve stem seals on it. Any suggestions will be greatly appreciated. Oh, and I'll be sure to take plenty of pictures for ya! Thanks!
