Over lapped or the valve and seat contact area was already to wide needed grinding before you tried lapping.

It turned out Idid the lapping job almost right. 'Almost',cause after lapping I only should have had one slight tap on the valve in order to be connected well to its seat...

Do you have any bench flow charts so I can compare mine with them

I'm sorry, don't have any flow charts,just Dyno run chart. Btw, if I had some flow chart you cannot compare those cause your engine set up is not the same like mine. My opinion.

Only true way to move and narrow the seat is to use valve machine with three different angle stones and then a light lap. Top quality valve work should not require hand lapping.
