Mixing RR ratios? Worth it?

[cobra1923]

Here's another one I have been chewing on. I am running an E cam that I had laying around. I also have an extra set of 1.7 RR along with a set of 1.6 (both the blue FordMotorsports). I've always liked running the 1.6 to keep the geometry the way Ford intended.. but would it hut to run the 1.7 on the exhaust side and the 1.6 on the intake side?

That would take my E cam from a 498/498 to a "dual pattern" 498/529.. thought?

Should I just leave it well enough alone and runt he 1.6s?

Im running the 1.7's on both the intake and ex. And the motor pulls hard. Just doesn't cams as hard as it does with the 1.6's.
