I have 3 sets of flat tappet springs and my markings on boxes has faded. Im virtually sure Comp 980's have yellow paint so its the other 2 sets im unsure of. Its down to the oe's and a set of Crowers. One spring is taller at around 2.146 others are around 1.934. Im thinking the taller spring is the stocker. Thanks alot guys. btw springs are for sale.
