Are there any advantages to running heads off of a marine 350? Could they possibly help to make more torque or are they the same of automotive? Thanks George

Same as automotive, but possible with hardened exhaust seats. I know that marine Vortec heads are teh same as teh automotive ones.
If you find a Vortec marine intake, grab it, as it is MUCH better than teh truck L31 Vortec intake.

yep...Mercury Marine is across the street. The marine engines are basically GM motors, then adding marine accessories,intake,exhaust,etc..
