magnum r/t heads

[71dustar]

Starting to build my motor and just trying to scope out parts. I have a 5.9 magnum motor i'm tearing down this weekend and my goal is to make 450 rwhp or so. i know the magnum r/t heads flow better than the reg mags do but do they make the r/t heads (big valve) in aluminum?

on mancini's site they show big valve cast iron heads and then they show the aluminum heads but doesn't give the size of valves. i'm assuming its the stock 1.92" valves.

Just head over to Hughes Engines' site. They have a bunch of information.

450RWHP is a HUGE stretch without a stroker, nitrous, or blower. Mine was ran through a simulation at optimal temp, and broke 414BHP, and I'm using RHS heads.

The aluminum R/T heads suck. I don't think they even make them any more.

Your best bet is either going to be the Ebrocks or the EQ heads.

450rwhp hp might be a stretch with the stock Magnum bottom end...

oh i already know i'm stroking the motor to 408. i was just curious if they made alum big valve r/t heads. where is a good site to look up eq heads? what does eq stand for?

eq is enginequest. Here's a good comparison of bench flow #s
