My 52K has a bad practically missing valve guide on the rear Cly i noted two years ago when the last was tight trying to push in a feeler gauge the valve tip moved almost half way off the adjuster bolt.
Well with the guide that bad I'm surprised how well it runs.
Any way I recall someone saying KH valve had bigger head diameters. Is that correct? Are stem lengths the same?
I plan on having a new guide installed and the seat is likely wasted so rather then sink the valve I'd like to just cut the seat and size the valve head to suit. Were both valves in the KH bigger? i don't recall if it was the intake or the exhaust and it cold and snowy out in the garage...
Thanks and happy new year!
