302 timing with updated cam

[Farmall]

I recently installed a new cam (mild, for low end torque), aluminum intake and Summit four barrel (which looks like an unbranded Holly).
I was wondering what timing settings folks might have come up with for best operation and fuel.
Stock 6deg btc? I know the lobe timing is changed. In playing around I've run it up to 25btc. It also has electronic ignition.
At 25deg. I had to run premium and it screamed at high rpm, didn't keep it there long.

I always like to set mine at max timing, all in, and let the initial fall where it wants to. Leave your vacuum advance plugged in, idle up to 2500-3000 rpm and turn your distributor until you reach 38*. Lock it down and take it for a test drive. Tune your carburetor mix screws to achieve 19-21Hg from manifold vacuum. Set your idle at 700 rpm. Repeat until you get her running the best she will. After I swapped to a Duraspark electronic ignition system and set mine to max timing initial came in at 22*. I thought that was crazy but she loved it there.
