NHRA doesn't want to do their job on policing rules and for that matter what we pay for from them when we buy our memberships. NHRA is streamlining for their benefit not to have to enforce rules that should have been kept up with, like valve spring pressures. The cars in stock would not be running 1.0 under if the valve spring pressures where set to factory spec. for sure. The valve spring spec on my 302 engine was 96 lbs on the seat and 204 lbs open pressure, no way could you get the motor to 8k rpm. Now, they are changing gears at 8200 rpm.
My vote is to go back to enforcing an across the board valve spring pressure so that you have to use stock (buy in any auto parts store) lifters again.

Yepper......But how are you going to get the associations to change that rule? If I was still working the IHRA deal I woud push for it but I know it would be shot down. That would eliminate just about every NHRA car that wanted to cross over and the car counts are low enough already. NHRA would have to mandate it then IHRA would follow the rule change. All one can do is send letters to the powers that control this stuff and complain and try to reason with them about the cost and potential oil downs. With a head off already for a CC check and the valves out for a size check the checking of a couple of valve springs would take only a few moments. Let the stockers keep their crazy overlap and duration specs as that was a pain in the ***** to check.
