The intake valves are 1-7/16" in diameter as opposed to other 1500 heads
that use 1-3/8".  With the larger valves, one has to assume that the engine
is able to breathe more effectively.  The exhaust valves are the same on all
1500 heads.  Of course breathing entails all other components of the intake
and exhaust systems so your results may vary.

How did you determine it flows better? 
What valve diameter did you end up using?
Thanks!
