110% agree w/puller, wouldnt have much faith in protesting a head, they are making recast heads look very close in appearance to stock heads, heard some even have water lines running to them to trick the "tech crew", and a part number isn't too hard to acheive... I am all for recast heads, but not just allow them to a certain group!!! kinda like that guy w/the sharpie, making things bigger than they are supposed to be!!!!!
