Why is it so hard to get good advice !!???

I went out for a drive today.
First up, it idled lower than before. I made no adjustments to the distributor or idle set screw. It also idled smoother, as if the additional lift tamed the cam's duration ??
I have about a 50/50 mix of 110 and 91 adding up to about a 1/4 tank because I just dumped the last 2 1/2 gallons of 110 in before I changed the rocker arms. ZERO detonation right now, I'll have to wait and fill up with 91 to see how it runs on straight pump premium. It may be a moot point though. As is, it does feel a little faster than before, but with all this chatter about how much faster the car could be with a bigger cam.....I may be tearing back into the engine sooner than I thought.
