Any one ever use these? they claim that they will give you more clearence behind the headers so that you dont need to dimple your headers and things of that nature (they are a shorter design then standerd plugs) was thinking of giving them a try, as it stands now iv got wbough clearnce for regulare plugs once they are in but not enough to take the plugs out with out taking off the headers 
Would like to get some honest opinions from people who wont give me the run around just because they want me to buy them hah. iv always used standerd acdelco in the past.
