| would it be wise to stick with the stock cams for an engine upgrade? looking to do 500whp. I really dont want to upgrade cams, but if i must then i guess i would. But is it really necessary? thinking about a whole built short block and the heads pretty much refreshing it back to stock and possibly some bigger valves. and i figure if i ever felt the need to upgrade cams in the future after that i could just put them in then, but im not sure...does the whole engine need to come out again to redo cams?
