Thanks for the spec. on that sub. On a quick check they are right. I'll post the numbers later. I thought they were interchageable. I was thinking honda would have them ground to perfection, but nothing is ever perfect. A thousanth of a mm. is a very small thing.
Well Sub, the two sets are almost the same with only .001 in. as the biggest difference between the new and the old of the rear Cams. The new exhaust lobes have a difference of .001 in. between left and right as well. That's not much. Both are within spec. This will be my first attempt at setting valves that use shims as well. So wish me luck. Thanks again for the info.
