Used Westcoast head, YEP7000 for Yamaha 701. Used OE type 61x head gasket (Which we have). Has YEP7029 29cc domes. Depending on your porting, elevation, etc it should be aprox 175-180 lbs on a stock 61x cyl. No returns on any used parts. domes are very clean, some minor pitting on gasket surface, as you can see in the pictures. Please email with questions before ordering, thank you
