Rocker-arm ratio on 2.0L, 914 motor?

I thought it was 1.3:1 for both the intake and exhaust rocker arms. Anyone know the exact number?

How can you tell the difference between the different arms?? I have noticed that they have different markings? I have a set of 8 1700 ones, and in the pairs that they came off the engine in - so I could guess - but if anyone has any hints it would be good!

Intake and exhaust are physically different- big time....None of the rockers are perfect ratios, they vary.

I'm going through three sets of 1.7s, to get the ones with the MOST ratio I can find!
Just bought another set off of Ebay too! $10!

The cost of turning down the shafts for a Type I, 1.4 ratio, is prohibitive and the Mazda
rockers dint hit the stem right, so "Ya do, what ya have to do!"
