i have a customers car in that was rebuilt elsewhere last year. and his schnider cam went bad on 1 lobe. schnider said the edge of the rocker pad had been hitting the cam, and to use a .160 lash pad with this replacement. well.... it has 170s in it(and nothing available at motorsports) so i thought i would try one and see where the geomerty looked. its bad. i have the adjuster all the way down, 1 lash pad cut to 160 and still have less than 0 clearance looking at the springs they are at proper spring installed height , but there is a .060 extra shim under the spring to do so.
looks like i get to redo someones valve job, so i can get the valve tips to a lower position.
