Magnum intake drilling plate project

Does anyone know if a reverse jig exists to drill for a magnum style intake to be installed on an la style head? Want to install trick flows on a magnum block with a Mopar m1 2bbl magnum intake. Was thinking if not I can maybe use a spare magnum kegger intake as a jig but not sure how I would keep it in place while drilling...
The thing about redrilling a beer keg is, have you REALLY looked at it? Is there a way that the angled bolts can even fit without a bunch of milling, or crash through into a port runner? Is there even room to insert the bolts without cutting into the TB mount so you can reach bolts through from inside?

I would think it much easier to figure a way to mod an LA intake for injectors. TB and sensors are easy, by comparison
