GENUINE OEM YAMAHA F350 PORT SIDE CYLINDER HEAD. REMOVED FROM A GOOD RUNNING ENGINE!!! Compression was good, and the engine oil was clean! The water jackets have MINOR corrosion!! Overall this is a nice clean used port side cylinder head!! Taken apart is a clean environment and professionally!! Removed in good working condition! THESE ARE USED PARTS!!!! Parts may have knicks dings, scratches and in some cases light corrosion. I will add a note if there are any other known issues! I do not sell junk!!! Look at the pics closely as that will be the item you are purchasing! For certain parts, I may have more than one in my inventory. I typically choose the worst condition item for pictures though more than one item may be pictured, so you may see slight variations in what you receive, almost always for the better! THE LAST PICTURE ON MY LISTINGS IS TYPICALLY JUST A REFERENCE FOR INVENTORY PURPOSES! I stand behind what I sell, check my feedback! I do make mistakes every now and then, but if there is a problem I will make it right. THESE PIECES ARE TYPICALLY ONLY INCLUDED TO KEEP ASSEMBLIES INTACT! Feed back is very important to us, we are a small family owned business. WE ARE NOT OUT TO RIP ANYONE OFF OR SELL JUNK!!!! I will work with you to make sure you are happy! Just send me a message… Every case is different, we will work it out. From there the cost is up to you.
