<< Here's the problem, just checked the compression today:

 1    100psi
 2    100psi
 3    150psi
 4    155psi

 My book says that the min is 118psi with a maximim variance of 44 psi
 between cylinders.  The rings have only about 10,000 miles on them.  Anyone
 out there have any suggestions. >>

Bad news, whatever the cause. My guesses, somewhat in order:

Pistons in #1 & #2 installed upside-down, and have worn out the cylinder walls
Ring gaps not spaced correctly on installation
Broken rings
Burnt Valves/Bad seats
Cracked head??

Use your trusty vaccume gauge to check whether it is valve related. My guess
is, it is not.
