Eye, all new bearings and seals (and gaskets), get the small Summit Racing cam and roller chain kit, 4v intake (if you don't have one already), 4v carb (if you don't have one already, look at a spread-bore), and as long as you're placing your Summit order, a vacuum gauge. When the engine is all back together, tune it to death (or life, actually), and you'll see the best performance/economy that you'll be capable of.
You are going to hate headers, but if you must, DON'T wrap them in heat tape, and DO use Stage 8 brand locking header bolts. Build your exhaust true duals, no more than 2.25" diameter, as free-flowing as you can legally get away with (Cherry Bombs, baby!!!! ).
The trick is to modify your engine for low speed torque, NOT high speed horse power.
And learn to drive watching the vacuum gauge, trying to keep the reading at the highest number you can muster. High vacuum=low fuel usage. :B
