Problem going with headswap before exhaust?

My apologies in advance to Hammer if this isn't the place for this discussion...(we can PM this discussion Shannon, if that's the case)

1) I know that normally, headers are a PITA to install. With the head/intake swap, is this now an easy mod to make?

2) How about a set of cams (good performance gain, but nice for a daily driver...) added in?

3) How about lowering the compression a bit? You mentioned combustion chamber work. Any drawbacks here? (I'm assuming this is done on the cylinder head, or is that not technically considered part of the combustion chamber?)

It seems that with all of these mods (plus cat-pipe) I could be looking at, what, +100rwhp?, and similar torque figures? (20hp-catpipe, 15hp-cams, 65hp-PP bullitt intake/PI heads) do these figures look right? Or are they a more accurate picture of what is going on at the crank?

What total cost would I be looking at? (You can certainly PM this bit if you don't want to broadcast the quote.)
