You'd probably need to proceed by getting dimensions from currently available
gaskets, and doing a couple trial fits.
The aftermarket gaskets I've bought aren't necessarily a perfect fit and
sometimes require a little 'stretching' to
fit. There may be a little variation from manifold to manifold, so you'd want
to try a couple at least, and maybe
oversize the holes a little bit.
With the price of copper these days they might be more like $15-20/ea; that's a
lot, but I get tired of changing them out.
