one of your posts said you were going to put in a 7.5 power valve in place of the 6.5. you should be going to a lower #.

Check your vacuum at idle. Being a drag car you can use anything under the vacuum it idles at. 3.5 might be a good choice.

It sounds like a lean pop but it could be the power valve leaking too much fuel into the engine???

Have you tried a different spring yet?
