+14 on the 255's. I cannot believe how much better my bike runs now. What heat?
And now that I run Redline oils, along with all of the other work on the motor, I have had to put a cover over my oil cooler just to get my oil temps to 200*F.
I ride in the 1800-3000 RPMs in most cases with this setup and it pulls like my tractor. No pinging, and stock it was pinging on a semi regular basis. I don't about anything other than HD 203, andrews 26G and they were in a 95" and the 26 was better than the 203 a bit.

I would go with Wood 6-6s. I had them in a 103 that did 100hp/110 tq with over 100 tq at 2K. Stock heads, springs, compression are all good for the 6-6s. It pulled right to 6K.

Just my .02

I don't understand your answer at all.

They're both basically the same bike, so why would one be preferred over another in these applications?

I know iclick will have to put in his $.03 in on this also and he's pretty sharp on this stuff but IMO there are better choices than the 255's.

Here's my 3¢, as predicted. I have not dyno-tuned my bike and thus haven't viewed any charts on my setup, but I have tuned with the PCV-AT and now with the PV and sense no dips or any hint of tuning issues with this setup (96/255). I am also having no heat issues, and the opposite is the case here. Even in our 95°+ S. LA summers I rarely see front head temps high enough to trigger EITMS (290° on this bike if I had it, which I don't), and it stays at 225-235° at slow highway speeds. In summer, oil temps never exceed 205° as long as I'm moving, and above 220° is rare even in summer traffic. The highest I've seen in 2½ years is 240° in a major traffic snafu this past summer, and has only exceeded 230° several times since installing the cams, no higher than with the stock cams. Even with an oil cooler these numbers are abnormally low based on feedback from others, even those with other cams installed. A friend with a 103/255 combo runs generally hotter than mine, but he reports that his oil temp did not exceed 230° this past summer. I don't think heat is a common complaint with these cams, and I don't recall hearing of any except in your case.

Again, I appreciate your experience and that you've chosen to relate them to us in a forthright and honest way without denigrating the cams as generally unworthy for anyone. I don't think the trouble you had is typical, at least based on the feedback I've seen, and it certainly isn't in my own personal experience.

Based on this profile I would suggest either the SE255 or Andrews 48H. Both are quite similar in design and are world-class stump-pullers of the Harley cam world, although there are others that produce a bit less CCP that would work well in the 103 too. You can find lots of feedback on the 255's but not much on the 48H since they're fairly new and there aren't many who've tried them. Those who have seem to like them very much, as do most 255 owners.
