Savage Dias,
You're almost there, but not quite. You still need the RTV High Temp Gasket Seal. (amatuers....sheesh

)
At least you'll only need cutting disks for the dremel, but make sure you get alot of them. The other bits in the kit are of no purpose. But the cutting disks do break pretty easy, especially when trying to carve compound curves.
But all that you need to secure the engine, of course, is duct tape.
