Magnum heads worth the effort?

yes, remanufactured fully loaded from Odessa. 300 for the set from a FABO member here. I just put the hughes spring kit on them, and I massaged the bowls and intake ports a bit.
Did the heads already have valves and Springs and you just changed the springs? Was the 300 including shipping or any transportation? And how much were the springs and shipping? I'm not even going to get into how much time you put into massage of them LOL and the drill bits and sandpaper and lalala that you had to spend money on and had to have the drills and all that stuff...
