Good choice! I did the same with my 345. I pulled the engine out, cleaned it up and had my friend who is a mechanic do it. He only charged me a friend rate of $100. Along with the cam/gear and gaskets I also got a water pump, oil pump gear, gov gears and the upgraded fuel pump. I also replaced the radiator hoses and flushed the radiator out.
The upgraded fuel pump has a drain hose that goes down through the frame. The original pump doesn't have a drain hose and if it fails like it did on mine it sprays fuel on the exhaust. Luckily mine didn't catch on fire
