Tuning with jets, Power valves and an O2 guage

Today I spoke with Jim at Racer Brown cams. He has many interesting things to say.
First off he blamed the wide .056 quench and 10.7 compression for the detonation. He thinks that with quench, the compression wouldn't be a problem. He thinks I should zero deck the block and use a .039 gasket to obtain optimal quench. I told him I am not against pulling the engine if it comes down to it but I'd prefer to look elsewhere for a fix.
Jim suggested going with a thinner head gasket to tighten up the quench distance. This would close it to .044 while raising the compression to 11.03 to 1. He said the same thing I've heard before: Quench gives benefits that overshadow the common reaction to high compression. Every time I hear this, it sounds like the TV claims of "Eat more cake & pizza and lose all the weight you want!" It just seems too good to be true.
I've asked many people about quench. I've started threads about it asking "At what point of piston to head distance is quench no longer effective?"
I don't recall many clear answers on that topic. If I knew with scientific proof that at my .056 distance I had NO quench, I'd just default to the thicker gaskets like I did in 2006. It seemed to work then.
Jim said that the thinner gasket would get me into an effective quench and probably stop the knocking. He also spoke about another angle I never considered: There are cases where a bigger solid cam can actually increase cylinder pressure over a smaller hydraulic cam when you consider VALVE LASH. The Lunati cam has bigger lift and duration numbers but when the lash is figured in, it may be opening the valves later and closing them sooner. This could explain why the Lunati cam increased the cranking compression.

Finally, I added about 3 1/2 gallons of 110 leaded Sunoco and drove the car. This sucker is SCARY fast compared to before! ZERO detonation and more power than ever.
Okay, I've determined that the car will run stong without knocking. My goal still stands: Getting it to run on 91 octane knock free.
Head gaskets, thicker or thinner? Maybe both would help. I've tried thicker in 2006 and it worked then. Maybe going thinner would also work while making more power?
