I think that you'll find that NHRA doesn't want Stockers "crossing over" to SS!
I meant if the NHRA stockers wanted to run IHRA stock....... If IHRA changed the valve spring rule to a max seat and open pressure for stock IHRA would loose ALL of the NHRA stockers wishing to race with them unless they ran S/S because of the NEW valve spring pressure rule. .
