Yes, those are Mark IV heads and a 1994 is a Gen V block. The coolant passages are different but victor makes a gasket that will allow the use of those heads on that block.

I've run 781's with the stock peanut port TBI intake and it does give it more power, but you'll benefit more using an Edelbrock TBI intake. The Edelbrock intake still needs to be ported to match the large oval port heads. Or an easier route would be a carb intake with a TBI adapter.
