turbogrill Posted June 24, 2017 Share Posted June 24, 2017 Hi, I ordered some outer valve springs from MSA and they are less than 1" in O.D. From what I understand the O.D of the z31 should outer valve springs should be around 1.3"? Similar as L28? MSA says they sent the correct ones. Thanks Quote Link to comment Share on other sites More sharing options...
