dougs headers dont clear zbar clutch linkage

There are probably other issues causing that. There are so many variables with clutch linkage, that no one problem is an absolute fix for another. You just have to understand what is going on and adapt. Understand what the one or two springs that are there are for or what they actually do.
I am trying bud. Just frustrating. It worked with the stock slant 6 z bar, stock exhaust etc. Now with a tti z bar and spring I got from Brewers it just won't come back up. I confirmed it has the 3 prong clutch disc just like stock. I may pull the pedals and lube them to see what happens.
