I got some jb stick weld at orielly's and it worked out really good one tube will fill the area that you want to fill. follow the instructions and be sure to mix it together really good and it'll form a very hard surface that can be sanded into the final shape you desire and drilled to allow for your vent and IAC function.

I just used regular epoxy a couple of years ago on mine. Not as pretty as other fillers since it's not "metallic" colored. Devcon would have been my choice but couldn't find any locally. Make sure whatever you use that you rough up the surface pretty good so you will get good adhesion. Take your time and make sure you don't accidentally get any on the IAC plunger seat.

Most seem to use the putty type, though I suspect
its adhesion is not so great (good strength though
and easy to work). You want to be sure the walls
are wetting properly, might use a bit of the resin
side to scrub with until it shows great enthusiasm
for sticking.
I used JB-weld regular epoxy after cleaning the TB
and roughing the "pockets" where the epoxy would
go, for some better "tooth". I made little foil dams
for the IAC and PCV passages and then put the
first coat on thin, just to seal, and baked it in the
kitchen oven at 200F overnight. I then did two more
build layers (J-B has no "body" to it and will slump)
with an overnight bake apiece (JB likes a 24-hour
cure but I wanted to move it along, a bit). Pulled
the IAC foil dam out afterward with tweezers before
drilling the port back open.

Damn this stuff is fun!
