That is a good question. With my experience I doubt it. The F plugs do work fine in the bigger engines. The 302 plugs are $14.65 each.

200 is a bit high. Your glow should not be on above idle. You are advancing the ignition point too far with the glow on higher throttle settings causing excessive heat.
