RE: spark plugs on GT40 heads ?

Man, I asked the same question awhile back and they told me standard 25's would work but I didn't think that would be right. I was thinking of more around explorer heads but they are basicly the same. But yea go to the part stores and get the plugs for whatever vehicle the heads came from.
