Roller rocker choice for HYD rollercam/for High Miles-Full life

Hi everyone,
I am looking for real experience, not "these are work'n great in my setup" then find out 6 posts later they have 7000 miles on there high mileage setup.:rolleyes:
A bit of background specs on what I have. Springs, 400-450lb @ max lift of .590 to .640, max rpm 6000. Trick Flow 240 roller cam heads to keep velocity up for low to mid rpm max torque.
4.250" stroke 440 cam'd for 2200-5000rpm sweet spot. Everyday driver in New Mexico.
55miles to closest store.
Aluminum is out for material cycle life with roller, flat lifter spring ok, roller spring no.
Comp now has steel rocker but upper push rod/adjuster upside down for shaft oiling, don't know
when they changed as I used them in years past.
Oh, I have built over 350 automotive and diesel engines as a trade/business over 30yrs but none in the last 12yrs. A bit out of touch with what is new. New rockers/parts ect. out there that I know I don't know about. Basis for my question to all of you.

Thank You everyone,
for your help and input.
Rick
PS: Sorry everyone, I somehow missed a very good super response posting
about rocker arms a few pages down. If you have anything to add here that would be great. again sorry for not looking far enough ahead or just plain not
seeing your awsome other responses in the other post.
Thank You all again,
Rick
