Valve lash should be .004 to .006 inch. But before you finish the job, check to be sure the valve guides are deep enough into the head, that the rockers do not hit and bottom out. That is what usually bends the push rods. Either that or valve sticks. Valve lash is not problem. As long as it has clearance.
