In addition, the 79 140 used special high compression heads. You'll need a special exhaust filler block kit (similar to the 392000 kit) and a machine shop will have to deck the exhaust chest once the filler blocks are installed.

If it's running good, leave it alone. It's not worth the cost for the extra HP.
