no, not at this time. i was more ruminating on the "where" point of lift that the pendulum swung and if there was a kind of rule of thumb that could be somewhat proven out by data or a detail analysis.
it was strictly a: at "x" lift point it is considered that headers would be a worthwhile expense.
while we all know that there are benefits, especially on anything hotter than a stock cam, i was just curious if there was a direct correlation that could be kinda, sorta pin pointed on something more stock in nature.
but thank you for the offer, i may take you up on that in the future!
