I've been running the 829's in my 499 for the last 12 years. I've had a set rebuilt and replaced that set with new over that time period. No problems or failures in that time. My car runs low 10's and never sees 7000 rpm. Mild cam only .620 lift. fwiw
I had good luck with the 829s when I was running 10s with a smaller cam too. The whole going faster thing with bigger everything is where the problems started.
I should have included that info. It is an older cast iron RB World block . It is unbushed and yes I would like to but am on the fence about it . It’s another part of the budget I am balancing. It does currently use solid body solid rollers now. Oil pressure has been pretty good .
You will probably be a lot better off than I am. My block has huge holes in the lifter bores where the galley is drilled through.
