Message	I've done both on measuring port volume and both are right at dead nuts to each other with volume. Same as the chambers. Port flange area I've also seen to be the same with a variance due to core shift. I've ported both NA and TT heads and both do just as good as the other in terms of performance. I've seen NO difference between the two with the exception of what I've mentioned before.
