Any advice on my 440 recipe?

It will work well. I have used the next step smaller whiplash cam in a 7.5 to 1 440. It's 229 242 @.050. I ported my 452s and made 415hp 465 lbs ft on the dyno. I used a ch4b intake and a 750 3310. I just freshened the motor. It was from a 77 fury and had dished pistons. Just make sure you have around 20 degrees initial advance Mine idles great with a very nice lope. Thrott respone is great and it'll blow the tires off.
Use the 20 thou head gaskets.
Also I've used 2500 stall from huges in 2 different cars. One was a gto with a 400 and one camaro with a 383 stroker. Both worked very well just as I wanted them to. I'd use another one.
