So i'm looking at some valve springs on ebay that are listed as LS1 valve
springs. Comp Cams 918's (2481540642). Now the specs on them say that the
installed height is 1.8" which is different from the stock ones that fit my
heads but the outer diameter is the same. What (if any other than installed
height) is the difference between these springs and other springs. I'm
looking for a stiffer valve spring and am looking into any money saving
options that might fit my application. Thanks in advance.
