I am installing gt40 heads and roller rockers on my car. The stock pushrods @ 6.250 are not long enough. I used my pushrod length checker to try to figure out what length is needed. Should the rocker be able to move back and forth at all after torqued? There is pressure on the pushrod, it's not loose but you can push the rocker and it will spring back from lifter preload. At 6.300 there is no play whatsoever. Just wondering which way is right before I order longer ones.
