Will pass on your questions to Dema:

About how it goes.

I'm running 91 Oct with Oct Booster
Running 123 Ign on b20B curve, no vacuum advance, at about 8 deg BTDC idle

It goes like greased spit between 2000 and 6000 with a lovely hammer and anvil punctuation exhaust note, except I have a crummy M40 that vibrates severely above 4500 (inlet bearing or layshaft failure) I have a better one coming from Gregg Morris of VCBC soon to arrive.

I think it pings at high rev...but I don't know what I'm listening for. I'm installing an AFR meter next week (AEM style) for more diagnostics and for dyno prep. I had a stuck throttle episode yesterday, and I know it'll spin 7K plus (no load)...lucky not to break anything.

HSR's running on 192.5 main jets, std needles, #25 pilot jets, plugs look clean, with a little Oct Boost red color. I have an inconsistent idle speed problem to solve...acts like the slides are sticking. I think it's because it takes part throttle to run at idle (1000 rpm), which means I've got main jet bleed adding to pilot jet...a throttle blip SOMETIMES cures it, but not always. I think the part throttle is adding to my dieseling effect as well.
