Well to do a bit bench racing for you, your 7.32@95.3 1/8th is approx an 11.6@118 1/4. I am having to guess the weight of your car at 3800 with you in it? so that gives you currently 511fly hp with those 906 heads.

Bolting on those sidewinders at 84cc will drop your comp a bit if you don't mill them to 79cc but no matter, if they really flow 290cfm I would think conservatively you would get around an 80hp increase over stock 906's which should give you 590 fly hp, that in a 3800lb car should run around 6.80@100mph in the 1/8th, or 10.84@124 in the 1/4. Only numbers but the Wallace Calc has been pretty accurate for my cars against my 1/4 mile timeslips. Good luck with it.
