Btw, in my case we are talking about the tip of the valves, not the valve seats or the bottom of the valves. the lifter is sitting right on top of the tip and if the tip is worn it 'may' leave space between the camshaft lobe and the lifter. I will definitely follow your suggestion and see if there is any space between camshaft lobe and the lifter resulted by the valve tip wear though..

Thanks again,

Ozzie
