just to clear this up I have been doing tons of reading on probetalk for my engine build this winter....and even started a post on there ...TO DATE THERE IS NO RECORDED KL01 CAMMED KLZE THAT HAS BROKEN A RETAINER
look at this 323 with a curveneck ze hittin over 9000rpm...with interprep valvesprings and cams on STOCK ZE retainers and locks
94+ there is an improved retainer http://videos.streetfire.net/category/M ... 1c52ba.htm

The KLZE retainers are based on production date and not what cams they came with. late-94 saw a proper intake valve spring retainer which is NOT prone to breakage. Early ZE's, both with KL31 and KL01 cams had weaker/improper fitting retainers that were prone to split. I have a late 94 ZE that came with KL01 cams, when i removed the first retainer in my DE spring swapover I saw that the retainer was of the updated kind and thus havent bothered changing them. I now have KL31 cams in this engine and synthetic 5w-20 oil and I hit the rev limiter several times a day with no worry at all.

This is NOT TRUE. There is absolutely nothing wrong with the springs. The problem is indeed the early-style retainers. Not only were they too thin around keepers/locks, but the keepers/locks also did not sit flush inside the retainer, eventually cracking (splitting actually from the outward force of the improperly seated valve keepers).
