Default Breaking valve springs!!

I can't seem to quite breaking valve springs. I've broken three in the past year. Anybody ever had this problem?

Is the break in the wire clean or jagged?

You have a harmonics problem. . .valve float, spring dance, low seat pressure.

A set of the patriot gold duals with Ti retainers and Super 7 locks will be loads better than the stock lock setup at supressing the harmonics. The springs are really nice too.

After seeing how much the stock lock moves in the radial groove of OEM valves and aftermarket valves, I would not recommend any performance upgrade that included using the stock type OEM locks.

Checkers,
Take your stock lock and move it up and down in the bead groove of your valve. Now imagine that movement at high rpm in a modified LS1 plant. Individual engines have their own frequency characteristics. ..end result their own distinct harmonics. Your combination doesn't agree. I would look at going with a dampered spring to absorb the harmonics.

Up until this year, almost all guys were using stock locks. They are not the problem. Your springs are the culprit. It'd be nice to know what springs you are using...Are they single or dual? If the springs are stiff enough, the valve locks should never move.

What type of springs, retainers, and locks would you go with? This only advise West Coast Performance has given me was to go with newer style Rev Duals which is what came in the heads.

well, there's your problem. so many people have the rev duals break, and break often (don't ask me how i know ). i bet if you get a different dual spring, like the patriots or cranes, that this problem will go away. the rev springs are total junk, IMO.

With all the people I have spoken with I am in complete agreement with you. Thanks for the help. Just need to know which would be the best.

I have never heard of a Patriot GOLD dual breaking. They are some bad *** springs, not to mention they are pretty too.

And they are a great deal too.
