Default Once the fence...

I put a set of newly refreshened heads on my shortblock. I tightened down the heads and performed a leakdown test. Three of the cylinders leaked down between 3-5%, cyl 4 leaked down at 8%. I traced the leak to be on the exhaust side, both valves. I could feel a bit of air coming out of the port, confirmed it by spraying wd40 in there and it misted out. I guess what I need to know is, is 8% acceptable? I wonder if the valves will "settle" a little tighter once everything is broke in? On one hand, I guess I could take it apart while it's still out, on the other, I wonder if I should bother......
