For Sale: RHS Aluminum Cylinder Heads removed from a 500 HP Mercury Marine Engine. Heads have less than 30 hours. I replaced these with the stock cast iron heads to accommodate new Gil Exhaust manifolds. $1,000 firm. Contact me at (563)590-3233, Tom, Dubuque, Iowa.

This is for a set of Heads for one engine. Thx Tom

Do you have 1 or 2 sets?
Part # ?

I have 1 set. I will list the part number that’s on the heads

The part number on the end of the heads is 11301. There is also the following numbers near the valve springs: 606750A And M15

The part number identifies the heads as cast iron and not aluminum.
