This is a hypothetical question, say you weren't limited by NHRA rules, but had to stay with the same foundation 500 CI, 4.9 BS, NA and RPMS. What changes would you make to your motors to get the most out of them?

I've heard of the pneumatic valve actuation, I've googled the F1 fuel but haven't been able to find anything concrete on it, would it be that much more beneficial than say a q16/c45?

Yes. Look up Renault F1 engines, they perfected pneumatic valve springs.

Use this text in your search "Renault F1 pneumatic valve springs"

I was asking about the valve adjusting procedure you mentioned back in post 6035

Was curious if you would share your valve adjusting procedure, not cam design secrets.

"Most cannot adjust their valves properly anyway. Their parts get hammered and they blame the lifter"

My statement about .050 valve events is about cam design not valve adjustment procedures.
