Well, if you go to the dealer, you get the bare head and you pay retail.

You still need to setup the head with proper valves, springs and guides.

I've had a great experience with the head for the 617 by using Metric Motors in California. They can supply a brand new head and set it up for you.........probably at a decent price..........and it will be to specification.
