Can there ever be too much venting?

does the steam reach the ends of both mains about the same time? If so, then the main vents aren't the problem- maybe slightly larger vents on the rads would help.

I'm trying to evaluate the main venting on my one pipe system. One main is 46.5 feet long and supplies 4 rads. It is vented with two Hoffman 75's. The other is 53.5 feet and supplies 6 rads. and is vented with a Gorton #2. All main piping is 2 1/2 inch.
The problem is the shorter main heats more evenly than the longer one. And the rads. at the end of the longer main only get heat on the initial call for heat in the morning. In other words, the longer the boiler runs, the better the heating at the end of the longer main.
All rad. vents are new and sized accordingly.
Do I need another vent on the longer main to add to the capicity of the Gorton #2?

No, the steam does not reach the ends
of the main at the same time. The steam gets to the end of the shorter
main everytime. The main with the Gorton takes two or three minutes longer. Would it make sense to increase the size of the all the rad. vents on the longer main?

Check
that #2 to see if it opens fully. If not, call Gorton and have them ship you another one. You should be able to hold the vent vertically, blow into the pipe connection and feel little if any resistance.
If your #2 is OK, add another Gorton #2 to that main. There may be more than usual resistance in the piping of the main, which a second vent will offset.0
