If you use a 351W head on anything other than a 351, you'll need to use 351 intake gaskets, unless the heads are later than 77. The shape of the water ports is totally different than the 289/302 port. The front and rear intake gaskets should be tossed and silicone used, but the side intake gaskets for a 351W must be used in this application. The other thing is that the 351W uses 1/2" bolts, so you'll need to use a special shouldered washer to be able to bolt them up to a 289/302 since these motors use 7/16" bolts. Edelbrock makes the special washer, it is part # 9680
