The IHRA rule is no T&D or Jessel type system at all. If its a stud type OEM mounted rocker system then it has to stay that way. No conversions!!! If is an OEM shaft rocker system then shaft rockers are OK on combos that use them from the OEM such as the FE Ford, 273-360 Mopars, 361-440 Mopars and Hemis and others.
No trick set ups and must maintain OEM rocker ratios only. No under cut cam lobes with non OEM rocker ratios. No Jomar type girdles at all.
