vlave spring\seal fitment
how do you use the rubber valve seals on a 351c head when using a dual spring with a dampener. it just doenst fit even when the springs are to fit the correct aplpication. are they not needed for my 1\4 mile car? i cant see them stopping much oil anyway. has anyone dealt with this in the past. i know it sounds like a really stupid question but i guess i should know.
