Humm....
Just a guess, But due to the cross section of the pic of the intake runner, I would say a 1g /ubbthreads/images/graemlins/idea.gif
Another guess, shipping from NY to OhiO, on appox weight of 53lbs, in a box 14X8X22 would be in the $65 range
BTW when did Ohio get two i?? lol
So $550 for a fresh built zero mile head + $65 (appox) = $615 appox total
Sounds like a good damn deal to me, the cams alone retail for $400, and about any sing spring and Ti retainer kit is $200
Add another $150-200 for a decent core to rebuild, and a few hundred more for the port work and other $150 or so for the valve job
