Question Need opinions on valve clearance

Just got through tearing off the valve cover and measuring the gaps and I found ONE intake out of spec on #4 - .009 (other one on same cylinder measures out to .0065). All are within spec on the exhaust cam.

The question is, do the gaps decrease over time? If they do, can I get away with leaving this be for now, or should I just pull the intake cam and replace what needs replacing?

They valves will pound them selfs it to the vavle seat after time and the clearance will decrease.
But with a loose valve clearance the end of the valve stem may mushroom. That will be bad.
If you have .003 extra clearance you need to make an adjustment.
