The factory valves of the ls1 heads can tolerate valve springs set ups for .625 lift?
Any of you with big cams and factory valves ever broke a valve because the valve sring pressure?

if your running the proper spring pressure with your big cam why would you break a valve . if your running inadequate spring pressure you can have valve float and the pistons can touch the valves or the springs can break all together and pistons will smack the valves.
