Beware the magnum eq heads. I see you're in Illinois too. On an extremely rare trip into Chicago (because I can't stand being there, any of Chicago gives me the creeps). I picked up a pair of "bolt on" EQs right directly from EQs loading dock for my wife's 360 in her Durango, with less than 3 hours of run time on a fresh engine I had a valve stickwill and kiss the piston. Fresh rebuild on the short block, bored 30-over and all. I ended up taking them off and then to a machine shop and had to pay for a valve job to make them usable. Pretty pathetic for brand spanking new parts sold as "ready to run out of the box" or "bolt on and go".
I ended up buying a used engine off of CL and put that in with those EQs AFTER I got to pay again... Initially to buy the heads then had to pay to have them redone. Totally unacceptable to me. I haven't recommended anyone to get EQ heads since. I can't
