I haven't called Gude yet, I was still researching. I found the head package at http://www.mmrusa.com/gudehead.htm for $1682 plus $500 core. Not sure if that is a good price yet, until I call Gude (since their site says "Buy Direct now and save").

Do you know if the valves are larger? Would you say that the head made a significant difference (over just cams and throttle body). If not, maybe I'll just go with the cams and throttle body.
