Kibble white valves

[sodslinger]

I wanted to start a discussion on valves, and more specifically the Kibble White valves I have been hearing so much about. Im building a street ridden rephrase xs and am doing a bunch of research on these xs heads. Im gona get my stock head on my flow bench soon for some port work, and was curious if anyone has experience with these valves? I plan on running either a shell #1 or XS-1 cam and not sure its worth the money. They claim to flow better and reduce valve train weight? Im looking to get all that I can out of this head with out going to extremes. Anywho thanks for the input.

Although not directly related, look at the threads found by doing a Google custom search on "stainless valves". The issues there were about inconsistent stem diameters, and the importance of quality parts...
