siwtching to Eddy heads on a 360

Has anyone had any unforeseen problems or modifications needed when switching to Eddy heads on a 360? I'm getting ready to put Eddy heads on my engine and wanted to see if there is anything to look out for.

My current set-up is as follows:
360 bored .030 over
stock crank and rods
KB Hypereutectic pistons
10.3 compression
iron J-heads
284/.528" Mopar solid (but changing to a 296/.557" Mopar solid this winter)
Edlebrock Victor open plenum intake
750 Holley double pumper
Spitfire headers (but updating to Dougs D-450 or new TTI full tube headers)
