Bout to replace my whole top end. heads, cam, pushers, intake etc. etc. is there something that is often overlooked when replacing this that i need to do? for example, im replacing the timing chain while I replace the cam for convinience and as I understand it, it is recomended.

 

lifters, valves, roller rockers, and gaskets (of course). Why are you replacing instead of rebuilding/reconditioning?

 

power upgrade, got a blown head gasket and i decided to replace my heads completely, and it was convinince to replace the lifters, cam, rr,and gaskets of course.
