don't pay more than $50 for a good set of e7's, period. FOx mustang guys like me give them away for free all the time.
They're not performance heads, and I wouldn't run them on a fresh install to save my life. Gt40 or gt40p heads remain the best bang for the buck on a budget.
don't pay more than $250-300ish for gt40 heads.
