Best Bang for the Buck Head???
Looks to me like he wanted to UPGRADE!!
He clearly states in his follow up reply that he is curious if the flow increase from porting would be worth x amount of money.
So put this perspective Brian, say 400 dollars later his x heads flow 250 cfm, say about a 30 something cfm increase and all within the .550 lift and under in the 'longevity street life' range. Now do you believe 30cfm/60 hp potential increase for 400 bucks isn't the best bang for your buck compared to spending 1500+ dollars for an extra15-20cfm the rhs have in the version you sell?
$400 vs 1500$
That's almost 4 times the money for an extra 15-20 cfm peak and a few more throughout the range , a closed chamber , and and an extra 12 lbs a piece.
Still the question is basically which upgrade will give best bang for buck.
Maybe the op can state a budget or future plans, otherwise aftermarket heads are incorrect for his app and he is already equipt to do what he wants to do.
