My Blueprint crate engine story - May 2018

U can use magnum lifters and oil the rocker cups through the pushrods if that's a problem
We used to race with stock rockers and you can make them work
if you see that the rocker is moving more down than up add some .050-.060 lash caps
(it's starting from the same place and all the additional lift- about 100 thou is down how do the rockers look on the valve stem tips at full lift)
on the pushrod end the pushrod should be working in the middle of the cup- both ways not from middle to outer edge
