    ya with some massaging they could lol. id just be afraid of running around with a stock bottom revving like that.

    i think the lsx heads do but the lsx is a 454 or are you just meaning ls motors because i thnk the ls1 heads do flow over 300. not sure.

      Stock LS1 heads flow in the 245 range and LS6 heads in the 275-280 range if I'm not mistaken.

          I wouldn't hesitate to run big heads, big intake, big exhaust, and smaller cam. Custom cam for the application. IN the end the amount spent is minimal over smaller stuff. Little more time fly cutting, little more patience with the tune, but in the end it will make way moooo powah!

Heads are converted to stud mount, and have larger valves. Pm me if interested.
