Just got the 383 back together and need to know what you guys think of the plugs. Thanks
That plug is too hot. You have too much timing. As said, too much never seize.
The ground strap says too much timing.
The shell says it's too hot.
The porcelain says it has too much fuel.
The fuel ring needs to go way down to the bottom .060 of the porcelain. To see it correctly you need to look down into the bottom of the shell.
