Thats weird, why 1.6 ratio for ecotec?
I'm pretty sure the stock ratio are 1.65 so why would they make 1.6?

pretty sure they are 1.65 just that it only states 1.6 on the website.
Sometimes with L67 people will upgrade cam, springs, rockers, the yella terra i would say are better for higher revs and stronger than stockers.

Roller tipped rockers have linear lift throughout the range. Stock/ parabola tipped rockers have a non linear ratio through the range.
Stock ratio = 1.65:1, the rockers I'm selling here are 1.61:1 Yella Terra rockers.
The difference in lift between 1.6/ 1.61/ 1.65:1 rockers will be max 0.010" at any given point even on a 0.620" final lift cam
They roll on the valve tip, buy em
