Alan, there is more power, so the engine needs less revs to give the same output, it was very noticeable at first (going up local hills), but not so now as used to it as it is still noisy! And since fitting the c.r. gearbox the car is much more usable and much better hill climbing.

The fewer revs per mile are only due to your higher intermediate ratios, nothing to do with the tappets, and in top gear there's no change. Unless, of course, you have a very special gearbox with indirect top gear.
