Default How many miles do you have on aftermarket valve train?

Looking for information on what people run in their cylinder head, and what type of driving and how many miles you have on these parts. It seems like many people rebuild their head using aftermarket valves/springs/retainers, but so many others preach about how the OEM Honda parts are superior. This type of information should help a lot of us determine what to use and what to really stay away from. I understand there will be some failures of every single part/brand out there. If people could share their setup, that would be great.

How many miles on engine?
How many miles on valve train parts?
What type of driving (DD, track, drag, weekend warrior, etc)?
All motor/turbo/SC?
Valves/springs/retainers brand?
What's your power level?
Any other relevant info?

can't contribute much here. OEM lasts a long time, that's for sure.

I've been running aftermarket "racing valve guides", that's all I've been told about them. I have about 10,000 miles on it, I don't expect them to be worn out, but we'll see.

I hate to bump this old topic but I wanted to know if people had a SuperTech vs Ap2 for people who are running Ap1's
I might even make sense for me to just go full Supertech over just ap2's

Anyone do this option?

I would put my bets on staying with ap2 for longevity/reliability over supertech. Farerra is better quality then supertech anyway and id still keep with ap2 unless I was forced to run them because of new aggressive cam/engine spec. But at that level of build your general expectation is giving up some Daily longevity for power anyway. If your just keeping with a stock spec/cam F20 just stick with ap2 upgrade keepers and thats it.
