Yes to the eddy magnum heads and this is what it says about the cam
" Our cam choice would naturally be a hydraulic roller, since these late-model Mopar small-blocks are thus equipped. We wanted to keep the cam specs moderate and streetable, so we decided on a 230/236-degree duration at 0.050 Comp custom grind on a 110-degree lobe separation, using Comp's XFI hydraulic roller lobes No. 3016 and No. 3037 on the intake and exhaust, respectively. These lobes provide very quick valve action, giving 0.576/0.571-inch lift with a Magnum 1.6:1 rocker ratio. The stock Magnum hydraulic roller lifters and lifter-retainer spider assembly were kept."
