Trackrash: I assume PMO "Anti-percolation" modification has been performed? If so then this partially explains your hard, hot re-starts.

Jack Stands: F26 emulsion tubes want larger main jets than F3s do which helps explain the large main jets for your application.

Juanbenae: Adjusting idle air bleeds (smaller) will allow tailoring progression/transition to use smaller idle jets while maintaining mixture strength for transition.

A 2.7 with compression & cams like yours would typically want 36mm venturis, 155 to 160 mains, F3 emulsions, 170 air corrections & 55 idles.

Double check your emulsion tubes are clean, fuel pressure is 3 to 4 psi, float levels have been set with the car on level ground and with engine running and finally check that side-to-side air flow balance is checked at 3000 RPM; have a helper hold throttles open or use a turnbuckle rod to replace the long link from bell crank @ #3 to throttle cross bar to hold throttles open.

Invest in AFR sensor to verify seat of pants performance and jetting.

I apologize for suggesting this since I do not know the symptoms of detonation vs. ability to rev: If compression is 10.5:1 and you are using pump gas with a single plug ignition then possibly you are richening the mixture with large main jets to overcome detonation issues.

Bottom line is best described by John Passini: "Suck it and see." You can postulate jetting but give the engine what makes it happy.
