Laecaon Posted April 20, 2014 Report Share Posted April 20, 2014 Yes they are the same, and there is an Outer and Inner spring for each valve. Quote Link to comment
datzenmike Posted April 20, 2014 Report Share Posted April 20, 2014 They should work for valve lifts to around 0.470". (check this) After this they could 'stack up' or bind. Quote Link to comment
