Need a little info on the 305 SBC 416 heads on a 1970's 350?

I am buying a stock late 70's early 80's model 350. I also have a 1983 305 with the 416 heads on it. My plan is to use the 350 and do the following: Install hooker headers, (cause that's what I have already) go with a performance dual plane intake, completely rebuilt qjet, running the stock 416 heads. I understand the compression ratios will effect the ability to run cheap gas, but i really will not drive the tuck much anyway. My question is what horsepower (ballpark) will i be looking at and is there any other cheap tricks (got this one from an older guy who runs dirt track) that will increase HP and torque.
