LS7 Lifter pre-load Ok so , I have been reading the lifter failure stories lately and just to verify everything before I do my lifter swap next week, I got the LS7 lifters which are now the replacement for LS1 stock lifters from GM correct? Also what is the suggested pre-load for these lifters? I have stock length chromoly pushrods too this is ok with these lifters for a H/C pkg right?

I just replaced my old stock lifters with the LS7 this weekend, and no problems. All I did was soak them overnight in oil and dropped them in the next day. I am running VRX5 cam, 7.400 comp rods....working great so far!

The fact that I'm swapping out stock heads for TSP stg 2.5 5.3 heads shouldnt make a difference either should it with pushrod size and these lifters?
