Heads?

Het guys. Im getting ready to buy a new set of heads for my L98 and was wondering what is the best type for our tuned port's? I have stroked my 350 to 383, I have the COMP XFI 576/570 cam, MSD 6 series ignition 30 lb. injectors, headers, 40 series flowmaster and many other add ons. I have ported the plenum some but still have stock runners and intake at the moment which im going to upgrade to a high flow setup later. I was thinking of going with the AFR 1041 but b4 I spend the $1500 I would like your guys opinion's because I respect all of you.
