Manley ti Retainer Problem
Have anyone had the stem sinking through the retainer.
I dyno my car three time and now all 16 valve stems is sinking through the retainers, now i'm in need of a ti retainer that will hold up to 10,500 beside these manley.
Any recommendation, let me know thanks.

we are using ferrea on our engines, (complete ferrea setup, valves, seats, guides, springs, retainers, and even ferrea keepers) the car made 8-10 pass's on the dyno, and so far has been down the track about 6 times. i also used this valve train on my street car last year, put a good 1500-2000 miles and never had a problem.
ferrea is the way to go.but i did use oem valve locks on the port flow retaiers and i have never had a problem.we are spraying 250
on a gsr w/that set up.

Stem sinking through the retainer is normally a sign of extreme valve float.
I love our SuperTechs. SuperTech pays top dollar for high quality titanium. You can buy cheap titanium from Russia but it is nowhere near as strong as the good stuff.

Agreed Supertech, i run all Supertech valvetrain parts and their pistons. You will not have any problems with their retainers, they have a few, even one that will accomidate lifts over .500.
you don't need to change brands, Manley sells a keeper to go with there retainer, if you use it you will not have a problem. You should buy from people whom are familier with the product and have some experience to avoid problems.
I do not use a stock keeper with anything I use because of the problem you stated. Seen to many destroyed heads to think otherwise.
