As it turned out all the rockers were 1.54s. Thought the suffix had to end in B2, but there were some ECG...A2 also. Compared the rockers with known 1.43 and there isnt a question, high ratio
.Today I was getting them and a bunch of other rockers together to go have the valve ends surfaced. Took apart a dirty assembly to add to the lot and IT had brass busings. After looking through the other assemblies found its likely match, and sure enough, there is another set of bushed rockers, 1.43. Hard to believe!
