Preventing bent timing rings

What are things that I can do to prevent a bent timing ring? I cut the comm on my motors at least once each race night and the timing ring is always bent when I pull off the endbell and take a look. What can I do to prevent my timing rings from bending, and will bent timing rings decrease performance?

Thanks

I had this problem when I screwed one screw all the way and then i screwed the other one.
I try now to scew them in the same time (first both at 80%, then totally) and not too tight
hope this helps .

i use a small jeweler's type screwdriver. it has a sturdy enough handle to unscrew tight endbells but its not "torquey" enough to bend the timing ring when you reassemble the motor. i used screwdrivers with large handles before and it seems that i overtighten the screws even when im careful, maybe because i cant feel the screws setting in with the large handle

Don't put a death lock on the two screws, it just takes a snug turn and that's it.

Only 2 things cause bent timing rings:

1) Over tightening the screws down. Lightly screw in each screw, when each has started to snug, tight another 1/4 to 1/2 turn. Thats all u should need.

2) Often overlooked but if you where around before rebuildable stock motors you would remember that we used to pop endbells off especially in pan car classes. Not as much an issue with touring car but still it happens. With rebuildables the timing ring prevents endbells from poping off, but the result is during a hard hit something has to give and to extent i think the timing rings bend. They are a soft steel and are probably hot during most runs. So stay off the walls will help reduce bent rings as well. The hits im talking about are side swiping walls and stuff. Anything where your car has hit something sideways.
