47 knuckle head valve specs

[46CHF]

I am currently redoing a set of 47 knuckle
heads.. with kibblewhite valves , valve guides and a set of Eastern Springs. any info on Installed height, installed spring pressure, stock valve lift, etc. would be greatly appreciated

I've been setting the valve height at 1.560" above the shoulder. The Pan spec of 1.500" is too tight with stock valve guides, and there's a risk of bottoming on the guide. The Kibblewhite guides are shorter, so it's not so much of a risk. Lift is .373" as the rockers are 1:1 ratio. The free length of the springs is listed in the text of the service manual.
