went in to parts store to pick up some new spark plugs, and i thought i was in school...the sales person gave me his 2 cents and then some!!!

he told me because im running a mild cam, headers, 650 carb., i should use a diff. spark plug! , now all what they had in the store was autolite(cheap sh!t)computer calls for Autolite 65, he told me to run Autolite 64, claims to be a better plug for my app! is this true or he is just lost in another planet??
