I'm rebuilding a 1976 360 that will have a 9.0 to 1 compression, a comp 262 to 268 cam, or equivelent. a stock 4 barrel intake with a thermoquad,or rpm air-gap with a 750 edelbrock,and headers. using this set-up will aftermarket heads offer me any noticeable power gain over the stock heads?

how are you getting 9:1 compression? stock pistons or stock type replacements will get you 7.7-8.2 compression with stock heads...
depending on what your heads need, it might be more economical to get a set of enginequest 318B heads....hughes has them new for $700/pr assembled with good springs, they flow about 30-40 CFM more than 1.88 valve smog 360 heads, and have a ~9cc smaller chamber, which will net you a .7 compression increase with the same short block over 360 LA heads.
I had a very good experience with a low compression (stock long block 360) with a comp XE262, eddie air gap, and an eddie 1406 600CFM carb.

stock converter, I'd go comp XE256 or lunati voodoo 60401 for a cam. my XE262 really liked the MP166K converter. if it were me, and if the heads need to be redone anyway, I'd probably run KB362's, and these heads from hughes. I'd still stick to my cam suggestion, unless you go to a stock high stall or ~2300-2500 RPM converter.
