I have a set of marine 351w heads sitting in the garage that I do not have a use for. Anyone interested?

They are in good condition and have been resurfaced,magnafluxed and gone thru at a head shop. I took them off my old engine when I repowered the boat last year. They just need a good cleaning then ready to go.

Could you provide the casting number from the heads or whether they are the 5/8" or 13/16" spark plug size. This will also determine the valve size and combustion chamber size. The standard 351 5/8" plug head is the smaller valve/larger chamber that was used on most 240 HP engines. The large plug/larger valve/smaller chamber head was used on the earlier engines (250-255 HP etc) and will raise the compression considerably on a later model engine. FWIW.
