Let’s forget about the poly lock issue just for now.
With any of the push rod lengths you have tried how close have you come to the amount of lift you should have in regards to contact patches one way or the other?
Contact traces that are towards the intake port side of the head mean your push rod is too short , if it’s the other way and on the exh side of the stem then there too long.
Make sure that if your using roller rockers that the rocker body is not touching the retainer.
As the ratio of the rocker goes up above 1.5 the push rods static position gets drawn closer to the rocker stud.
Do not minus your cams recommend lash out of your checks your making .
In general you want the narrowest patch you can achieve while being within .040” or so of the valve stem center while getting within .012” to .015” of the lift you should have.
