Magnum swap questions

The LA cams are ground for 1.5 rockers and the magnum is 1.6. Sure you will gain more lift but that is not how the cam was designed to run and might not be advantagous but probably will be. I would call a cam company and get there views on it like Rumble said.I do not see why you couldn't put on the LA timing cover and just block off the fuel pump opening.
