Ok, my mystery miss is looking like a bad bvalve...Have to do a compression check first, but am getting ready for a head swap. Haven't done these in about a hundred years...Need intake and head gaskets..Anything else I'm forgetting? Thanks! Den

Will be finishing up one myself this weekend, bent valve on #6 Intake of port motor. If you are using a Gen IV block like me you will need the Felpro Marine Head Gasket #17040, also use the associated intake and exhaust gasket set. Good Luck!!!

exhaust gaskets, valve cover gaskets (if yours are not reusable) and a tube of the Right Stuff for the front and rear of the intake.

You also need a bottle of Merc Perfect Seal for the intake gasket water ports, don't ask how I know this
