No one?

jegrmajstr--wish I could help! But I don't even know what Powernow Inserts are!

Should be OK if you really need to watch the $$$. There is a big o-ring at cylinder base so even if the base gasket isn't perfect it shouldn't blow out. A little Gasket sealer wouldn't hurt. My current base gasket is garbage and I still only gave a little seepage (It was a temp fix that now has a few thousand miles on it ).
But,
Spend the extra money on an OEM head gasket though. I know the Vesrah one I got was not very good, other brands may be better. I bought a gasket kit and ended up raplacing the head gasket with OEM. A visual comparison will tell you if the aftermarket one is any good. It was pretty obvoius. The kit will include a base gasket and exhaust gaskets which you will also need plus a bunch of others you may need. The head gasket it the only one of questionable quality.
I know it's very tempting to go as cheap as possible, but it will likely come back and bite you (BTDT). Since you don't know the history of the head, at the minimum, lap the valves and replace the valve seals. I took mine into my dealer (who I trust) and had it done. I sent the cams along and had them do the adjustment. It saved me having to buy shims. They just put the correct ones in and kept my old ones for the 'shim bin'. The price was reasonable since they didn't have to deal with removal or instalation on the bike.
While you have the head off, check the piston rings and cylinder for wear. It may be a good time to get a hone and rings.
The leaky exhaust was likely making the bike run lean, but I would seriously consider replacing the intake boots.
You can end up with a partially rebuilt engine that may have issues in a few years or a mostly rebuilt engine that will last many thousand miles.
Your choice.
SkidMarx--that is some excellent advice. I had not thought of having my dealer lap the valves and check clearances….that is an excellent idea. I have been purchasing most of the new parts (OEM) from http://www.babbittsonline.com/pages/parts/viewbybrand/default.aspx . This includes new head gasket and exhaust gaskets, I have already replaced the boots.

As far as the lower base gasket, it was not the money so much as another order and waiting for it to arrive, I will check it close. I will look at the rings and cylinder as well.

Now the only question is, should I go ahead and pull the whole engine off and blast/coat the frame!
