I have been out for a couple years, and am gonna try to make a race or two this year,so I was cleaning my motor up and decided to pull the valve cover off and just see how dirty things were...while doing this I checked the valve lash, and was suprised to find that i had none. This is a motor from a fairly well known builder with one race since freshen up. The valves are not being held open (with the motor cold anyways)both pushrods will spin freely, but i cant get any feeler guage in. Getting it freshened up again isint really in the budget,So my question is should i set them to around 3 thousands, which is where i would guess they should be? And if i do set them, is there any thing i should look out for, iv set valves on cars and on flat heads but not these motors yet...is there a torque setting for the adjuster, do they have locktite? Any other tips? Thanks in advance
