Well like I said... I almost certainly would not go to a hotter plug after modifying it.
And if it was modified radically it would get a cooler plug for sure.
But it's like jetting... If it was white I would go with richer jetting or cooler plug.
Or dark brown...leaner jetting or hotter plug.
I would stick with the stock heat range plug and jet it to suit.
I thought you were going to Daytona Ron?
