Hey everyone. I recently did a top end build on my 1990 5.0 convertible. The build consists of gt40p heads, trick flow valve springs, E303 cam, and comp cams 1.7 roller rockers, stock push rods and Ford performance hydraulic roller lifters. When adjusting the rockers, I'm rotating the engine until the exhaust valve opens all the way and just starts to close. With the engine at this point, I adjust the intake valve to where I can spin the push rod with my fingers, then tighten a quarter turn more. I repeat this process for each cylinder. When I adjust them in this manner, it seems as though the valves are hanging open and the car won't start. Every adjustment procedure that I find, says to do it this way but just doesn't work. Does anyone have any tips or ideas on what I'm doing wrong? Attached is a photo of the type of rockers I'm using
