Through some miscommunication, I did not have adjustable rockers installed on my fresh engine as the Edelbrock RPM head instructions require. I have plain stock rockers. I have some sets of Isky adjustable rockers and a few sets of different length pushrods. My engine builder has set the spacings on the shafts already but due to health issues, I should probably install the rockers. Is there a technique found in a repair manual or book somewhere? I have installed solid lifter rockers on other engines many times, but not hydraulic lifters combined with adjustable rockers.
