    Stephen in CA


    Works great it fits the valves perfect. I used this with the Prox stainless steel intake valve kit. This item is a single seal, you must order one for each valve being replaced or repaired.

    Great quality

    This is a nice kit. Has every size I will ever need. All the new shims were very consistent with the measurements on the shim. They seem to hold up well with no complaints

    Good Product

    These are as good or better than stock ! I prefer the Titainium valves over stainless, and these have been great. 1000 + miles and clearance was still spot on.
