Well man if ya like to phone a friend or something go for it,!!! Like I said they looked EXACTLY the same, I am not the type to list something that its really not, just incase ya might be thinking that. If someone can chime in on this PLEASE do, all the parts that we took off were all aftermarket ones so it leads me to believe that they are also, exspecially that they looked the same, when were taking off the heads well the valve covers the dood even put better springs on the stock heads when he really didnt need to he even changed the pushrods also, shit the whole valve train was done at one point , so I would think there also aftermarkets... I dont know what else to tell ya!!!LOL
