you can run whatever head you like. it is not the fact of what valve angle or design is as much as what you want and if you want to be like everyone else. the big chief head is a great street head that will produce over 50+ hp over a conventional head. it looks really tuff when you pop a hood and see the massive heads in there. looks like a boss hemi or something. if I had them you bet I would run them. they like big inch's so don't be scared to go with a 598 or even a 632 they make pistons for the 10:1 compression so the sky is the limit here.
