Sparkplug wires

We had some bad flying weather here in upstate New York for about two weeks that ended last week. My plane was in the hanger for those two weeks. When I started my 0-320 the other day and did my runup, the right mag had about a 400rpm drop. To make a long story short I had two bad plugwires. I bought a complete new harness for both mags and still can't believe the difference. I get almost 50rpms more on takeoff. I guess 30 years is to long for plug wires. I think it would be a good idea to check the plug wires when doing an annual.
