jim,vikki said 7k3 heads were what was best for his motor.obviosly you know different.it dont matter to me.
It's all in your choices. And it depends on your budget. There's not a lot of difference between these heads, 6X, 7K3 or the ones mentioned earlier. The 6X would give you a few more HP just because of the chambers(slightly smaller). The biggest difference is that some need a rebuild and some do not. They are all great heads.
