No issues before just poor braking due to lack of vac. Yes I do have headers I have plenty of clearance from master (8")and dis block(4.5") as far as the lines the drivers side lines have about (2.5") and pass side I only have about 1 inch clearance. I had to lengthen push rod and I checked it is returning all the way even have about an eighth of an inch play in pedal. I also installed a proportioning valve under car at rear. Would the 1 inch clearance not be enough on pass side?
