Checked valve clearance.....odd?

[Raze]

Here are my #'s:

Intake
1......0.013
2......0.017
3......0.017
4......0.017

Exhaust
1......0.019
2......0.019
3......0.019
4......0.019

I had to spend sometime checking and re-checking to find the max spacing so these numbers are after many measurements on each valve when the cam lobe was perpendicular to the valve plate face.

The camshafts are in great shape and the valve plate/tappets? look new and un-worn so I'm guessing the engine got some love in the recent past. Only issue I see is #1 intake. What will a less than spec value cause? I'm guessing the intake will actuate 'too soon' and close 'a little late'? Do I need to change this out? I do have a slight intermittent stumble at idle, makes me wonder if this is causing it.

Thanks!

with the numbers so consistant, i would wonder why #1 is so far off. I would pull the wafer and make sure there is nothing under it. also check to see if it rotates in the socket and isnt jammed in there at an angle. With it that tight, you will float the valve and it will burn.
