We only used it on the starting line, never in the burnout.


I think David Reher is correct, the two step is hard on valvetrain. We probably shouldn't use it on the starting line, either.


I approach valvetrain in a pretty much OCD manner. I will saw I saw some very expensive engines that were damaged when things broke because small details were ignored. I saw a brand new mega dollar big block once, it had a pushrod stabbed through an exhaust rocker, and the intake lifter on that cylinder had the foot shattered.Engine had Holroyd rockers on it. Clark told me when I bought my first set, "take a 'tootsie roll', and polish every bit of the burr off of the pushrod cup where the punch makes the oil hole.' The engine with the damage had untouched rockers, the burr was still present, and the fracture where the pushrod went through started in that burr. I was stunned that all the rockers looked like that.
