because 7afe pistons are right about even with the head..you're more likely to fry pistons and rings on a boosted 7afe then you are to fry a head?
its preventive maintenance + upgrading
put if you're going to be in there anyways you might as well spend the extra few on some headwork...which won't really gain you anything
the 7afe is a DOHC motor controlled by a single cam..that sux for adjustment. the cams themselves are of conservative nature
and on a nearly 100k mile motor i'd be more interested in pistons before i would the head (besides valveseals which i would do as well)

if you feel so inclined and have a little time, grab a book or research porting and polish online...you can do it at home with a dremel tool for a small cost which is strictly materials ie dremel attachments
all roads lead to rome it just depends which way you want to get there and how much you are willing to invest..

also to quote oobe
"7afe pistons are like powder"
