What gap size do i put for the 305 TPI with corvette heads.
Whats the gap size that i should use on my bosch plattinum spark plugs. People have told me .40 or .45. Which is the best setting for hp and mileage. Remember i have a remanufactured distributor,Hypertech cap&rotor and coil with MSD 8.5 wires. thanks

If im not mistaken, stock gap is .035, but with your aftermarket ignition parts, you could probably go to more like .038-.040.
