Sounds like a nice combo for sure Corey...about the LS7 lifters, there was a thread on here a while back with pics showing that the cup on the LS7 lifter is taller than the original LS lifters, so if anything, it would require a shorter pushrod (not taking the cam base circle into account). But, as mentioned, they are the "new" stock replacement and have some room to play for preload range. There's a lifter preload thread in the sticky section of the Internal Engine Mod section that has some good info that you may like

The actual LS7 lifters are the same length as the stock lifters.
HOWEVER, the seats on the LS7 are slightly taller so shorter PR's will be needed. Some guys luck out and run the 7.4's but since those heads are different idk for sure what size you'll need.
