Sense no one answered, I will tell you how to measure it. Put a wooden dowel in the rocker shaft hole that fits tight (sand it to fit) find the center of the dowel, and mark it. Use a caliper to measure from the center of the pushrod socket to the mark in the dowel. Measure from the center of the valve contact pad to the center of the dowel. Express these as a ratio, like 1.124": 1.66" this is then placed in a calculator as 1.66 divided by 1.124 = 1.477 this is the ratio's larger number. Thus the ratio is 1:1.477 This is close enough to call it 1:1.5. I hope this is sufficient. JimN
