Its pretty aggressive yes, but the ports aren't as "gaping" as some people seem to think. It fits my header almost perfect. Also, the ports on the exhaust werent the only things touched, which I think is known. Another thing is how my header and downpipe are setup and the transition between the 2. Nothing too out of the ordinary, but some thought went into it when we welded everything up.
The car is definitely happy more so in the higher rpms, but I don't feel as if I lost any low end. Before I had the ported head for the month or so I had the TVS on I felt like it was a little pokey in the lower rpms like most people seem to experience, but after the head swap that seemed to disappear. However, I still start my 60 rolls in 2nd when I need to

A lot of it has to do with how much air you are moving. Like putting huge turbo cams on a car with a small turbo that just cant provide the airflow, a head with a ton of material taken out but running a 3" pulley on an M62 may not give you the most desirable powerband for example.

hmm...thanks bastards, stock will be plenty of power for my goals, YET all this talk makes me want to pull head and port exhaust...which if i did that, id be tempted to do pistons, possibly cams, valve springs/retainers, rockers, neutral balance shaft/balance shaft delete...
essentially a full build....
thanks ********!!!
