Exclamation heads

Well im just trying to find out the size of the rocker arms, and lifters in the lq4, on the ls6 and ls1. Oh and the size of lifters in the ls7 which to my understanding their the same as the ls2's.

Just trying to learn more about it thanks.

Are you asking what rocker ratio they are? All "LSx" but the LS7's got the 1.7:1 ratio rockers....the LS7's get the 1.8's. All the lifters are interchangeable between these engines as well, with only minor differences in cup height between the new and old which affects the required pushrod length.
