I'm adjusting rockers on my 272, I'm doing it the slow way, still 6 weeks till the salt is off the roads. I'm manually turning the engine over with a wrench, when each cylinder valve starts to open I adjust the other one, I know it's slow and time consuming but its that or help in the house with spring cleaning. Any problem with doing it this way?? Thanx, Gary
