Valve steamsm and roller rocker problems Hi guys,
i controlled the roller rockers and saw that the mechanic didn`t use lash caps for the valve stems so the rocker arms hit the valve spring retainer instead of the roll the first miles.
Technical it could not cause a damage that the rocker arm hit the valve spring retainer for a while till it was cut? The bearing from the roller rocker at the push rod side has to do the same work equal if the arm or the roll hits the valve spring retainer?
The valve steam is also too short to put a lash cap on it.
Now i drove about 6000 miles with this work without problems.
Should i look for performance rocker arms with smaller rolls than the golden crane race ones?
Do you know smaller ones with standard 1.7?
With the situation now, what do you mean, is it dangerous that maybe the roll always hits the cutters or would it had damaged the engine after 6000 miles if it would be a problem?
Here are the picts:

We changed the valves and valve springs at the AFR 225 heads to extreme ones to handle the boost problems.
Thank you

You need to either get new locks, or retainers....looks like the ones you have are running two different degrees....either need to run 7 degree on 7 degree, or 10 server on 10 degree.
With a matching set of locks and retainers the retainer will sit a lot lower on the valve stem and the rockers you have will work properly...
DO NOT RUN THIS ENGINE AT ALL with the setup you have in there now...you are very lucky the locks didn't jump out of the retainers and shoot all the valves into your pistons!!!!

Looks to me as tho the valves are jammed down into the retainers. The retainers, locks, and probably the valves are junk....[Valves likely have the lock grooves messed up. And, it will be some work to get them out of the heads, without creating guide damage.]
And, FIRE the engine "builder"....
