On Aug 16th I posted the problem I had with the E plugs and galling the spark plug hole, got many replies on what I should do. I want to thank everyone for their input including the criticism the ole SeaDog listens and I've come up with a plan. With winter just around the corner I'm going to leave the champion plugs in and when the snow fly's I'll pull both heads fix the spark plug hole in the rear head and install larger intake valves (1.9") port the intakes to match a 51mm throttle body with matched intake manifold . Then have a new dyno tune done. Check my post on the power X wing results.
