My main argument in the “pros” column of the discussion about the current valve job was...... they had already run solidly into the 9’s as they are.

After seeing them all cleaned up, my argument in the “cons” column is........ there is likely some flow left on the table as they are.

Hard to say for sure how much, or if it would even show up on a time slip.
But I’m sure the flow bench numbers could be improved some.
