366 Tall-Deck Tuneup - Pirate4x4.Com : 4x4 and Off-Road Forum

I'm getting my 73 C6500 with a 366 back on the road. My question is relating to tuning up the engine. What should the compression be? Spark plug gap? Timing? Valve gap for intake/exhaust? Idle RPM and anything else I left out. The truck runs a little rough and diesels but I think thats from the timing. I just want to get her running smooth again. Thanks!
