Do I need L92 specific valve seals for my L92 heads?
Looking at picking up some valve seals for my L92's. Do I need to get the L92 specific ones for my heads or can I use a regular ls based seal. The L92 specific seals have that built in base and the regular LS seals don't. Do the L92 specific seals not need a spring seat?
