Timing chain guides

[Force Induced]

So I've been going through my check list of parts and weighing out stock units versus after market piece's. I was wondering if anyone has heard of someone having issues with these when they get to the northern power levels? Lots of small parts don't get looked at till you cross that road haha. epper:

we sell the mmr timing chain guides, and yes, I believe they flex a bit at higher power levels
