Push Rod Rocker Ball
Many years ago I had a similar problem that I solved, to this day.
"No bent valve, minor valve float, rocker arm binding" ?
My case found that when the rocker arm exceeded its normal travel (valve float),
the pushrod seat edge contacted the side of the push rod.
This contact forced the pushrod out of alignment with the rocker arm.
Smith Brothers, a NASCAR push rod manufacturer, has the ability to install a "high angle" rocker ball.
The lifter side ball is the normal straight design.
These cost the same as the standard design, just ask.
This last week I received my latest order, ordered on 4:59PM Thursday, on Tuesday
Their ability to create a pushrod with custom length and ship in the same day states a well operated business.
Your case could also benefit with a "rocker arm pivot height check". I know that Mike, Dan, "the guys" are
very aware of the importance of Rocker Arm Geometry.
I always recheck this because it is so simple to "just mark" the valve tip with a felt marker
before I install the pushrod/rocker arm.
Then turn the engine over with the starter, reinspect the contact area of the valve stem.
