Pushrod length

[hogracer3d]

Playing around with a pair of 1.6 and 1.55 rockers as a pair on a cylinder, and as I was checking pushrod length, it seemed to like two different length pushrods, to achieve the same pattern on the valve, one with 7.900 and the other with 7.750.

Question is, has anyone ever experienced this before? And is it normal?

By the way, gen1 SBC, Yella Terra 1.6 x 1.55

yes and yes but that seems like a lot (.150") of difference for just 1.55 to 1.6.

i think i had .050 " with 1.5 and 1.6
