Valve stem seal question

Is it correct if a gasket set only comes with the little o-ring type valve stem seals? Is it ok to use these alone or must I rather get the larger cup type that fits over the top of the guide?

The O-rings normally work all right. How ever I all ways use the umbrella seals. And on HP engines I use the PC Teflon clamp on seals.

GM used the O-rings to keep oil from traveling down from the tips & getting to the stems. They used the thin metal shields that cover the top half of the valve springs to keep oil from splashing onto the stems. If you don't use the shields, you should use the umbrella seals.

chevy's are notorious for having valve seals go bad faster than any other motor. DO what you can to maintain longevity.

Thanks! Yes, I am using the shields. I was mainly worried about the Felpro set only containing the o-rings. The won't really see much racing if any, the same for towing and the only major traffic it will see is if I want to go show off at the office. Otherwise, it will be a weekend and maybe week nights car and to go to rods runs with.
