Default Power valves or no P/V

I know I'm asking a lot of questions and I dont meen to be a lot of trouble I'm just trying to get it all right. I know some of yall been doing this a long time and yall know the do's and dont's a lot more than me. so for Drag racing only is it a plus to plug the power valve and jet it up or is it just done for insurance against back fires and blowing your power valve out.
Thanks Andy

Racing - plug it and jet up
I don't go up as many (8 to 10) usually more like 5 or 6 but only cause I bracket race and running your carb lean helps its run more consistent.



Street - running a P/V will help with driveablity (low to mid range) in race trim, doesnt matter since 99% of the time your @ WOT.
Goodluck, Cp

I'm not really worried about blowing them out. I'm just wandering if there is a plus to not use them and just jet it up.
