It would have been good to see your numbers with the 1.92 valves in both the EQ and RHS heads as a baseline. If I remember right my stock RHS castings went 238 @ .500 with the 1.92 on the "as-supplied" seat. Your numbers seem pretty good for the bigger valve and valve job.

Yea, in hindsight (isn't that always 20/20?) we should have started with the 1.92, as I am now curious. We'll get to the EQ's, but I'm hearing 240-ish with a 1.92 and about 10-15 more with a 2.02, depending on the VJ from most everyone I ask.
Further update: We grabbed the other untouched (by us) "as supplied" head and moved the valve job to where it should be and here's what we got for the upper numbers: Lower numbers improved by the same % in at most lifts...
262.1 @ .500
263.3 @ .550
263.8 @ .600
so it sounds like the "as supplied" heads have the stock RHS valve job for a 1.92" valve, but supplied with a 2.02?
kinda like OEM mag head valve jobs are typically undersized to the point where a 1.88/1.6 valve will work in the stock valve job?
