Definitely want hardened pushrods. Go with the complete cam kit from either Thunder or Texas speed. You are also going to need a front cover gasket, front crank seal, water pump gaskets, crank bolt and new fluids. If it were me I would go tr220 BC I like thunder. But the Texas speed 220 would work just fine. I would also put a ls6 oil pump, ls2 timing chain and ls7 lifters in there at the same time but its not absolutely necessary, just more of an insurance factor
