For the 84 Hurst Olds 307 vin9 engine it shows .80 spark plug gap. That does sound like a lot to me. I got a set of ac delco plugs r46sz as the r46rz are not available any more. Should I still gap them at .80 or just go with a lower .60? I am just looking for some good advice as this is my first 84 Hurst.
