5.2L Magnum Heads, Intake, and Injection on a 360 LA Block and Bottom End

I know it seems counter productive, but has anyone swapped the heads, intake, and injection system from a 5.2L Magnum engine onto a 360 LA engine? I know there would be a compression bump up. I can get a killer deal on a 5.2L magnum setup off of a jeep, with fairly high miles. I'd basically use the top end and injection from the jeep and then megasquirt to run the injection.

Is this something I could get by on pump gas with?

I'm going to check my block date right after work.
