Lets assume for a minute a perfect 1.800 installed height (but I cant be 100%)
Springs claim a .625 lift....
Cam had max lift of .603....
7.425 Pushrods
LS7 Lifters (+.060 over LS1)
Stock Head and Gasket....
Could the LS7 Lifters and 7.425 even on a 1.800 installed height cause a bind or at least been way too close for comfort? I understand that they are hydraulic lifters and that its end user that should measure but damn .060 is alot to not know about...I wish GM advertised that!

Thats what I was thinking... I had no idea about the LS7 lifters...man Im glad I saw your post about that ****. I wont make the same mistake on this car!!
Did you measure this or read this somewhere?
I think I have both of those lifters, I remember seeing one wheel covered more than the other in one of the older sets of lifters.
Ill measure them and see the diffence in the height of the pushrod seats.
