Receive date has been moved up to tomorrow. I will post pictures and hopefully get some advice.
These are supposed to be stock replacements. Im not expecting much for $613.74 to my door!!

Best I can tell, the only real high performance head for a magnum is the Edelbrock.... Everything else is custom...
But for me, thats ok, the motor is all stock.

I appreciate everyones input, and look forward to hearing more after the pictures.
