You all make valid points regarding the valve interchange, and it reinforces my decision to stay stock VM. But cost was $7.50 for the GMs. I only looked at the valve though, I did not look at GM springs or keepers, etc. I think it is very wise for me to stay stock in this instance.

I absolutely agree.
The only thing any of us can offer at this point re: Duramax head parts, are ideas, speculation, and hypothesis.
We KNOW the VM parts will work. We just don't know how long, but AFAIK none failed near-new, and the great majority are still working fine 12 years on.

For those of you that have replaced your exhaust valves, did you only replace the valves and reuse the rest of your parts for each valve? I.e. keepers, springs, retainers, seals? I'm trying to decide if I should do this upgrade while I'm in mine. I'd ideally like to do it myself to keep cost down as I have already spent so much on all my other upgrades. I can probably manage just swapping out valves myself but getting too much deeper might be out of my skill level. Costs can add up quick if you replace all the valves and associated parts on top of shop labor fees too.
