are unorthodox racing cam gears any good? i looked through the forum and couldn't really find an article on them. im building a LS cylinder head, everything from the head studs and head gasket to the throttle body. i heard skunk 2 cam gears slip around higher rpm's. I have the UR pulley's on my car now and they work pretty well, just curious if their cam gears are as good as their other ones. thanks.
