Howdy, Vintage dudes. This is my first time in the Vintage forum, so be gentle. I have a buddy who is building a CB 450 race bike. He wants to build an engine, specifically, he wants to have the head done (i assume a valve job and porting) I have done a little searching and found a few names: "Buff" aka Todd Henning, and Kenny Augustine. Lots of dead links. I saw that Buff posts here, so I will forward the telephone number (since the website is on earthlink and is FUBAR'd.) Anybody else know a good ancient Honda Twin engine guy? I know nothing about these bikes, when someone says "Honda Twin" to me, I think Hawk GT and RC-51. Thanks for any help.
