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...
What about buying a single plane that available (Trick Flow) and using a 4 to 2bbl adapter?
@Siciliano15 , don't take what I type below personally because you're new here. For the good of the community here, it would be the best way to operate a tool-sharing system.


At one point I was trying to just buy it from him and get it back into circulation and ONLY lend it to members who have at least a YEAR and MANY posts, aka "Well known Members". Everyone is flaming this guy from Canada but remember, someone who was trusted with it, from here, LOANED it to someone with a single digit post count and had just joined FABO! That guy needs every bit of heat that the Canadian is getting.
