Threads look great - just make sure that 'extended tip' doesn't hit the valve. I don't tend to run extended tip plugs (due to very high valve lifts) - just something for you to check!

On the other hand, if you're going to rev the heck out of it and don't have a tach - then run extended reach plugs. When you FLOAT the valves, they'll hit the plugs and close the gaps, which acts like a 'mechanical rev limiter' . . . ask me how I know these things! LOL
