Throttle body.....
I A 52mm TB also gives a 10-12 crank hp gain after the heads are done, according to the book (TB was next in the sequence). You can always pull the 52mm TB off the car and put the original back when you sell--I did it. If you're good, you can do that with the 1.6rockers too.
I think you are smart to leave the cam alone because it causes more trouble with the timing chain system than it's worth. Keep your LT1 timing set (although at 75k maybe replace the chain with a new stock chain).
