Has anyone run into valve tip geometry problems when going from stock rockers to the Harland sharp?When I switched rockers ,valve guide wear was inhanced ,tip indicated wear pattern to run center of tip at valve closed to outbd edge of tip at full valve open,I know this in not accepted.Pulled heads installed longer Ferra valves + .100 bronze guides.Pattern on valve tip was almost perfect but still favoring outbd of valve tip at half lift,installed Crower solid lifters that sit .070 deeper than stock,rechecked tip pattern and results was perfect contact inbd of center at valve closed,dead center at half lift and mirror image of inbd but to the outbd at full lift.
