if you got an elcheapo scanner/copier printer thingy, simply scan the manifold and print it out on fairly thick paper...like 200+gsm. snip snip, some silicone, instant gaskets double up if you cant get one or two sheets of thick stuff.

file the ports/flanges flat and just use silicone with no gasket at all is another option...

That's a great tip about the scanner, but I remain skeptical about using silicone on anything exposed to gasoline. I've had it turn into jelly over time and fail, not to mention filling the inside of your engine with bits of silicone goo. I will always install intake and case gaskets dry. Just saying...

yep, i personally use non hardening aviation sealer, or nothing at all. silicones for gutters!
