With longer valves you'll need longer pushrods. You'll need to use a checker to find the length you need. You can't guess at the length. .100" longer valves doesn't always mean you need .100" longer pushrods. Lash caps, if there's enough valve stem above the retainer locks to use them, will add even more height to the valve stem that the tip of rocker sits on.

Checking all the measurments. There shouldn't be a problem but make sure the bottom of the retainer doesn't hit the top of the valve guide/seal at full lift.
