1990 la roller 360........cam question

Have a Howard's Cam's "retro -fit" LA hyd roller cam,in my Magnum. Lift .515" intake/.520 exhaust. I dont see .525-.550 lift ,a problem. The ,heads/valvetrain ,the limiting factor. A better idea: What do,you want it to do?
And how crazy,you want to get?

friends say i'm "crazy" all the time.........lol.

i'm just wondering if u can use the stock lifter configuration, get some moderate lift without hurting anything, there will be probably eddy heads and some nice roller rockers on top......
