speedmaster 440 heads

Runner is raised but extended out far enough that a standard intake bolts up.
looks great
I received a pair 2015 casting victor style heads from procomps..
Did you have to 're-drill' the push rod tunnels ?
Did you fill them with your own valves? The one I got came loaded and the intake valves are longer what up with that?
Off-set rockers which brand are running and what off-set?
Is the use of a blower motor for the passenger compartment heater out of the question w/these heads on an A-Body mopar an w/RB engine in it?
what about push-rod length?
Did you have to get longer push-rods for the intake since the valves are taller?
thanks...
