Engine Running stock plugs in my aluminum heads

So my car runs so much better with the correct ( longer spark plugs) I just assumed that the aluminum heads would use the same as the stock heads do. After two years of pulling my hair out it finally dawned on me I was running the wrong plugs.
You know what happens when you ASSUME? It makes an ASS out of U and ME......
