Default Popping sound near redline

I don't often run my '92 LT1 that hard, but when I do keep my foot in it til it shifts into 2nd gear at redline, just before it shifts it makes a popping/backfire type sound. Is this normal or is it because I should blow the carbon out of her more often?

If it's not hitting the limiter, I'd consider the valvesprings. They might need replaced.

I'd change the ignition coil, first.
