Already know how to do it, just need specs, no point in ordering the book when some one can just tell us/him.

You could also try playing around with the clearances and see if you notice any improvements in power. Closing the gap a little on both intake and exhaust might net you a little more top end power if you have a few mods that have improved the breathing.

Hmm..............well I dont know why there is two different specs listed. All I know is that the book I got from Honda is specifically made for the preludes. Anyone know why there are two different specs listed?
