Stock springs are fine with ER rockers on exhaust valves.

The fact you're buying double the springs for no reason? Plus double the work for install? Up to you I guess, but the intakes require 105#s when doing any higher revving.

He was referring to the type of spring needed. Not a sparkplug.

Autolites do have a 103 and 104 style plug, but that's for another post
