pushrod length with TSP 5.3L heads
I will be using a TR 224-112 cam, TSP 2.5 5.3L heads, new stock LS1/LS6 lifters, stock rocker, etc. I will be using the stock GM head gaskets. TSP recommended 7.4's while Patrick said he would probably do the 7.425's. What do you guys think?
I am not sure if one is easier on the valvetrain or if one will keep it quieter?

7.400 will work but a bit noisier (less preload)
