360 heads on a 318 LA

I read a few pages of How To Build HP Chrysler Engines by F. Adkins. He seemed to endorse putting swirlport heads from a 90 ish 360 onto an older 318 LA. He stated that this combo when used with a manifold for a 360 seemed to be a good power house. Has anyone here done this? Does it seem to be a better combo than a stock LA 318 ? Or would it be better off trying to get some Magnum 360 heads and adapting them?
