Mike, I had a similar situation but installed them anyway. I had a noticeable loss of power. I waited for the ECU to relearn the timing but it never did feel right. I had to pull them and regap to the manual's specs before the engine felt like its old self again. This was a couple years ago, so I don't remember what the gap was. I would check each plug and set it to the manual's specs. It will save you time and trouble.
