100 horse shot of nos for 440?

Head gasket should not be a problem. 200 shot on a 440 is only .45hp per cube. I was spraying 225 shot on a 170 slant six (1.32hp per cube) with the stock steel shim gasket, and 10.-1 CR.
Thanks for info I'm hoping someone can tell me approx horsepower this motor will put out before nos
