318 rebuild/overhaul kit

Also, if I'm planning on pulling the engine to thoroughly clean it, it shouldn't hurt anything to replace all the gaskets and seals right? I mean, if compression is good, I'll just keep the head gaskets for later.

Are there any special tools I should look at getting? I did notice when I set the ignition timing i don't have a way to monitor RPM, but after setting it, I revved it up and the timing mark (on the balancer) would move away and sometimes return to were I set it. Isn't it supposed to stay ther the whole time?
