For your LT1, You can get just as much HP out of those heads as the Alum versions, just have added weight. A set of stage II heads ( good porting, larger valves ) and a 305 cam should put you in the 350HP range, moving up to a 306 or GM847 cam would put you in the 370-380HP range but at that point you are going to loose some drivablity in the low RMP range, not going to be very smooth driving in traffic, will need to deal with some cam surge. So at the 375 HP range a LS1 with a hotstick and heads would make the same power but be a bit easier to drive on the street.
I'd go LS1, probably a bit easier of a swap as well,

Granted the LS1 may be a tad easier to make power, but for the cam that is in my car, its def drives better than you would think. A good tune does wonders to having a larger cam.
Also, wouldn't an LS1 require new K member etc and custom headers or stock ones and custom Y pipe?
