These decals are made to apply onto the raised letters on your valve covers.  Fit all of the SV family of engines, from 152-392ci.  Available in nearly any color, just ask!
We ship these in a 3-pack, so that you can use one to "learn on".  They are fairly difficult to install properly, but far from impossible.  I've not had anyone call or email needing replacements, so the extra one must do the trick for most folks.
