Junkyard 360 LA Head Porting Questions

Yeah, that is a more realistic number to go for, considering it is only a 360 and seeing as it could possibly come out of a durango. I just like the idea of a hot street motor to wipe my friends chevy's off the map with. (they are starting to brag about how much better chevy's run than mopar's.)
Durango?? They didn't start building those until, what; 1998 or so? That's no LA, that's well into Magnum territory. A little different can of worms, but they're a great starting point, too. Decide what you're starting with before you start accumulating parts (even in your head), there are some differences that can influence which direction you take.
