The 360 build that has more turns than Willow Springs

Here is a new consideration:
I'll need new pistons for this 360, likely going from the .020 to .030.
Tomorrow I'm helping the FABO member @RBConvert pull the MP 360/380 from his '68 Dart. If the teardown show the engine to have pistons that are .030 over, what are the chances of those pistons working in the 360? I know that the deck heights of the LA series is supposed to be .019" taller than the Magnum series. The use of these in an LA would probably be a difference of half a point. The crate engines were supposed to be just over 9.0 to 1. A thinner head gasket could make up for some of that difference in deck height.

It would be nice to save the money and just reuse the Magnum pistons. I'm not looking to set speed records with this engine. I had planned on keeping compression closer to 9 to one anyway. I didn't want to be obligated to using premium gas all the time.
Does anyone have some feedback to this idea?
