Good quality cylinder head that fit perfectly. Gaskets and other supplied items all worked fine except for the carburetor studs which was too long. Had to remove and replace with the ones from the old head.

This was part of an order to rebuild a Honda GX390 that had lost an exhaust valve. We rebuilt for just under two hundred dollars or about a quarter of the cost of a new engine. It was worth a try and so far is working well after six months

I like that it came assembled and is identical to the part I was replacing for my standby generator. All I needed to do was torque the head and adjust the valve lash. And the price was right.

Replaced a 420cc briggs and stratton head with this and functions identical. Just have to reuse the pushrods. Back to operational again

Head broke on first use. I have never, in all my time rebuilding small honda motors, had a head break where the spark plug seats. This is by far the lowest quality after-market part i have ever bought. Definitely regret this purchase as now will do the rebuild twice with factory parts.
