First of all i want to hi to everyone. I'm new as of today and this is my first post. I have got a question for anyone out there who may be able to help me.
Question is : How can you get the proper geometry on a 20r or 22r head without cutting the rocker stand?
Bigger base circle- smaller base circle? Longer valve stem- shorter valve stem? Any info or help will be greatly appreciated. Thanks

 

Can someone point me in the right direction of someone who know how to do this. Thanks S Renzi
