um... a rebuild kit from atkins? it's all there i guess. as far as reliability, i'd say get an aluminum radiator, electric fan, and good thermostat. lets see... 3mm apex seals are a good reliability mod, do regular oil changes every 2000-2500 miles... um.... drive it hard once a week or so to open up 5th and 6th ports, as well as to clean out the engine. exhaust isn't really going to make it more or less reliable in my opinion... i guess run premix if you're up to it, and i can't really think of much else
