I have to replace the valve seals on my 99 LS head and was going to go ahead and replace the entire valve train with Crower parts...valves and the dual spring/Ti retainers. My question is, with the new, and I presume stiffer springs, will I just be eating away at my stock cam? I'm holding off buying cams until I put in a turbo down the road some time. Thanx.

 

NO, that is why oil is use for and that why there a way you could adjust your valve clearance. Stock cams is built really good so it should not be a problem.
