I did read that article before and it is a very good article with lots of info. I was just wondering if there was a way to do it without tearing the head off. It might have to wait and be a winter project. That would be a good time to swap the cam then also. It has a comp XE268H now but I think I should go bigger. Not sure what cam yet but I will worry about that when the time comes. Thanks for the reply though.
