magnum or la that is the question

Ok guys and gals, this is my first thread so please be patient with me.
The patient:
1972 Plymouth Duster
318 la
stock engine. edlebrock performer intake. holley 600 vs. and headers are the upgrades

So here's my plans, I want to go efi. The holley just doesn't work the way I want it to. I've come up with a couple of different ways to do this.

Option 1:
Keep the 318 with stock bottom end. Edlebrock allum magum heads(to help bring compression up), thin mr gasket head gaskets(to help with compression). hughes air gap efi intake. holley hp/avenger efi mpfi.

Option 2:
I own a 99 ram with 5.9 magnum and blown transmission. This could be donated to the Duster. Completely stock to begin with, but it will get upgrades eventually.

So that's my thoughts, now what's yours? Which way would you go?
