After pulling all of the valves out, the guides seem to be ok. But I ordered a new valve seal kit and all it contained was small round "O ring" like seals that fit into a groove near the top of the valve stem. THis is fine except I found there to be umbrella seals in addition to the small round seals on the intake valves only. Was this a factory thing? Why only on the intakes? Did someone put these on by their own accord? Should I just put the small round seals on and call it good? Thanks Fellas, Brian
