Re: double hump heads on a 78 engine

Good advice above. You said your engine was a 78 but not what vehicle it's in. If it's a 69 or newer with a long water pump and passenger side alternator, you are asking for lots of other problems.

Once again, if your vehicle uses a long water pump, you would be better off buying brand new Vortec heads and intake IMO.
