Need Help on Heads on Gen 5 454's
Neighbor has a pair of stock 330-340 inboards out of his sea ray both standard rotation.Bought a offshore boat with no engines .Wants to use these,>reason for removing them was one had a blown head gasket and he re-powered with fuel injected engines.Now he is removing the heads and was asking if a head and intake manifold change would give him a little more HP.Does not want to get into the lower end.Has small ovel port heads on it now.Just want a little more than 340 HP Just a river boat .Wants to use the engines because they were well taken care of and are closed cooling system .Any thoughts or help would be helpful. Thanks JOHN SR
