Mancini/HS 1.6 rocker not giving me the lift expected

I ran into this recently with Hughes 1.6 aluminum rockers. I was missing out on over .045 lift with the correct length pushrod and finally saw the difference of the adjuster location to the centerline off the rocker shaft on half of the rockers I received.
Look over your rockers and use a straight edge along the adjusters as a guide.
