score! but i need help

well, my birthday is commin up & my parents asked me what i want, and i said a junkyard 360 (yeah, you guys convinced me), and they said okay.

so then i started thinkin about all the stuff I'm gonna do to it, and thought "hey, why not pull off the heads & stick them on the 318 so i can get that 400 horse while i'm building up the 360?"

Which brings me here, i have no idea what year of 360 to ask for, or what kinda work i'm gonna have to do on it to reach that goal, or if the lifters & stuff on the 318 heads are gonna be compatable or anything. Plus, i've never ported heads before, and have heard numerous horror stories.

So what all am i gonna need to do? Also, what year should i get & are my lifters & such compatable? Here's the parts list i got when i got the car, the guy was building it up to this article in hot rod magazine;

sbm ignition package
sbm v/c package
comp fuel filter
mstr. kit w/ pistons
true roller timing
high volume oil pan
headman headers
edelbrock rpm intake
carter afb comp series 4-barrel carb
comp cams xtreme energy 268


thanks guys
