    Default Valve Spings backwords?

    Can you install valve springs backwards? I removed the intake and exhaust spring from one cylinder on my buddy's motor to check the rocker geometry and when going to re-install them i wondering if there was a possibility of being able to install these backwards. From what i can tell, the answer looks to be no, but figured i would check. This is a double spring deal, i made sure i labeled exhaust and intake so those went back into the correct location.

    If these were a triple-spring, 1.640" dia, 2.200" (or taller) installed height deal, then it is very possible that the valve springs have a specific top and bottom, each end identifiable by how the wires are cut at each end of the coils and also the way a chamfer is put into the outer wire's OD at one end.

    In lesser double-coil valve springs such as you describe it is less likely that there is a top and bottom of the valve spring, and usually they may be installed either way. Close up pics would be best, or a valve spring brand name, part number, OD, suggested recommended height. If you are concerned because this thread is in the v-drive section you may PM me the pics/part number, etc.
