Best Bang for the Buck Head???

..based on a stock stroke 10:1 340 i don't think you'll gain much over the X head unless
you are going with a radical cam....

I don't intend to go with too radical of a cam. Just one matched well with the combo.

Thanks for the input. You really don't think the RHS's or Eddy's would perform better than the stock X heads? That's interesting.. Would love to get others' opinions on that...
