Run leaner. No more than 20 ROP. Use Lucas Upper Cylinder lubricant. Lucas Upper Cylinder Lubricant, 32.0 FL OZ, Yellow$8.87Walmart. Ream exhaust guides every 500 hrs max.

This is a place to start. http://enstromhelicopter.com/wp-content/uploads/2016/11/Magneto-maintenance.pdf The dual mags can be a bit more troublesome if not done correctly.Mike I've heard of e-gap but it's above my pay grade and need to find someone who speaks bendix mag. I have the bendix dual mag (one drive two mags) it's got about 220hrs on it since install. I'm assuming you can check in place but need to remove to adjust. Almost zero space between firewall and mag.
Last time I had a Lycoming exhaust valve stick it cost me an overhaul from cam and lifter body wear. Too much surface pressure between components I assume. Do whatever satisfies to ensure that didn't happen.

…. I get better results using Lucas upper cylinder treatment to reduce carbon buildup then I ever did with MMO. Cheaper too.....
Camguard is supposed to help. Anyone seeing morning sickness with Camguard?
