I was looking on Jegs and they have a kit for a V8, 1.6:1, amc for $130.  What else do I need measurements on in order to see if this, or possibly a ford or chevy kit, would work?  Thanks

Well, I droped a set in today; I'll let you guys know how good they work.  So far, my butt-dyne did not feel any difference, but I guess the mpg will, so I'll keep you all posted.  I did this mostly thinking it would lessen the noise in the valves, and to a degree it did, but not as much as I was expencting.

Since I saw this thread was brought up, I figured I'd update everyone on the results:

To be honest, the only difference I have seen is that the engine takes longer to heat up (less friction, I guess).  MPG and power feel about the same (I guess there could be a slight increase in power, but I cannot feel it).
