on the motor ive been talking about. from the wrecked car i bought i pulled out and after i washed it i took out the plugs cuz im gonna put some colder ones for n20, well when i took the out they were all platinum and one was a standard plug , but it was shorter than the rest. the heads are the edelbrock performers, and when i went to the speed shop the guy asked me that there were two different sizes, which one are the right ones, thanks.......

 

Just have him put the model of you're car into the computer, if its not VIP then they can give you the right plugs.

 

yeah but he has eddy heads, did you try puttin the one plug in another hole? are they the same thred? or is the one just shorter than the other?

 

yeah they are the same thread but shorter

 

the hole were the standard plug was at looked like the threads were a little stripped or just might have been the anti sieze **** on them cuz i put another plug in the hole and went in fine.
