Myron,

Please check with your tech guy in Div 2. I don't think you can put bigger Dia springs in a stock head.. If your engine came with 1.440 dia. springs, you can't open the spring boss to run 1.550.. Just like you can't match ports to gasket openings, No-grinding at all ??? So, save time & money, check withyour Tech guy & he will help you out ... You are right about the rule book being vague ...Hope you are doing well...
