I'm just curious what 1972 Buick 455 heads are worth. I know they aren't the 67-69 400 big port heads, but they aren't the "open" emmissions heads on the 75 and 76 models either. My reason for asking is that I went to RockAuto.com and I can get a pair of 72 Buick 455 heads, delivered to my door for under $600. They are remanufactured and guaranteed. Just curious. -Josh
