I found these heads they are 396 heads 702 casting freshly rebuilt, the guy will take $350 for them, my only concern is the stock valves, I would hate to put in new bigger valves since they were just rebuilt, any suggestions? and yes it is just a street engine I want to hot dog on the streets and rip the tires up every now and then... any info/advice is appreciated.
