Magnum intake on LA engine??

OK guys, here is one for those with detail knowledge and experience...

I have a 318 with a DIY fuel injection system (Megasquirt) My current intake is a 2bbl 360 intake which i have modified with thrrottle body and injector bungs.

Looking at the "beer keg" style MPI manifold of the Magnum engines, this is a much better intake. Propper individual runners, good volume plenum, etc.. its all there.

Now, here's the questions..

First of all, does anybody know if the ports and water passages match up bwetween a magnum intake and an old LA style head?

And secondly;

The Magnum intake has holes for vertical attachment bolts. Does anybody have any idea if it is feasible to drill new angled holes suitable for the bolt pattern of the LA heads? Is there enough room??

I have a complete Magnum intake on hand for a good price, but that doesn't help if it just can't be made to work for me, so any input is much appreciated here!

Thanks! :glasses5:
