Hi
Thanks for any response. I just bought a car with a Hemi. I know very little about the Hemi. It has a 572/272 Comp cam. 472 ci with 11.5 compression. Also has aluminum heads. I need to adjust the Hartland roller rockers. What are the spec's and any help you might be able to give me. I screwed around with cars along time ago, so I do have some knowledge.
Thanks Again
Ray



Same rules apply as a wedge. Is it hydraulic or solid. I find the best way is to do each cylinder one at a time. Roll over the engine until the exhaust valve just opens, set the intake lash (or pre load). Roll it over somemore until the intake valve opens and is just about closed. Adjust the exhaust valve. With a hydraulic, about 1/2 turn of preload from zero lash should do it.
