EQ Magnum head max lift?

Hey guys have a few questions. First off im building a 360 magnum for my Aspen. Im going to be throwing on my set of EQ heads I had on my LA318. I called Racer Brown about a roller hyd. cam, hes a super nice guy. Upon talking to him he was asking about the heads. One of his questions is if the EQ heads will handle a .544 lift cam or what exactly is the max they can handle without machine work? Im using currently the PRW 1.6 roller tip rockers with hughes 1110 springs, but want to go with Hughes shaft mount conversion rockers. Which that brings me to his other question. Will the rocker hit the retainers at .544 lift? Does anyone know or can anyone tell me how to find out? My heads are currently off and the one head is completely unassembled. Any and all help is appreciated. Thank you!
