Did the owner elect to replace the guides as well? I would assume it was at least considered since heads were out and valves replaced? I only ask because I am curious of a price for this setup installed.

Since the OP is pretty clear that he isn't going to respond to this thread, I would like to continue the discussion. Also, this isn't directed at him nor is it meant to be a criticism. He is intending to add headers to get back the "Lost low end torque" he sees with this cam. I am not sure what he is seeing from the dyno. I compared the torque readings from the stock cam with the STD graph on the K501 cam since they are the same format. At 2100 rpm they are dead even at 360 lb ft. At 2500 rpm they are still dead even at 380 lb ft. At 3000 rpm, the stock cam only pulls 5 more at 395 ft lbs. Hardly noticeable on the graph and never noticeable in the car. At 3500 rpm, the K501 seems to be ahead by about 2 or so with 410. This is at the upper limit of what I would consider low end torque. By 4000 rpm, which I consider the mid range, the K 501 is killing the stock cam by 20 lb ft. That is quite a lot. It gets stronger, of course, as the rpm goes up. To me, according to this dyno test, the K501 kills it on the top end and doesn't lose ANYTHING on the bottom. My guess is that with a set of long tubes this cam won't just regain the lost bottom end torque that the OP "sees", it will actually beat the stock cam all the way down to the 2100 rpm point that is reported in the graphs. From my experience, if you find a cam that can add a bunch of top end without actually losing anything on the bottom, you have something special. I am impressed.

First off, I apologize for my absence. I have been hospitalized 3 times within past couple of weeks and am just beginning to recover enough to get back to work.
We completed the Kooks testing shortly after I made this thread, however I haven't had the opportunity to post the results.
The Kooks 2" longtubes performed as expected and showed gains throughout the powerband. However, even with the slight loss of low end torque BEFORE the headers, the car performed very well. In stock form the car went 60-130mph in 8.10seconds, with the Head/Cam/Intake it did the same in 6.98 seconds. Now with the longtubes, it runs 6.68 seconds 60-130. I will compile all of the data and post a more detailed thread within the next day.

Here's the graph from the Vbox with the before/after Heads/cam results
Thank you!
