I have a 2007 MerCruiser 496 425 HP with an OM serial number prefix.

What is the part number of the correct head gaskets to use? Can you use Fel-Pro? Genuine Merc part numbers to use are?

Also, complete engine gasket kit part number?

Hi, just redid a head on my 496 ho and used napa for felpro head gasket($40 compared to mercury $248) and valve cover gasket($21.95 for both sides compared to mercury over $250 for one side) and intake gasket ($109 compared to mercury $275). Get heat exchanger seals, thermostat and seal, and exhaust manifold gasket (one piece)from mercury. I have the napa part numbers if you want them. Todd
