Not a guru but can tell you that if you talk to the HQ guys, they will tell you that don't expect the numbers advertised on their website unless you combine their cams with their heads. Doesn't mean the cams are not performers; just a heads up.
I would elminate the 510 just because I have never seen impressive dyno numbers from that cam.
That leaves the 6-6 and the 37. I am an Andrews fan, good performance without the aggressive ramps and potential for a noisy valve train that sometimes accompany Woods cams. The 37 would be my choice.
Someone, who is a guru once said "the Andrews 37 may not be the right cam but is never the wrong cam". The last build I assisted a friend with was a 95" with cleaned up stock (no porting) '06 heads with static CR set at 9.8 and it made 93HP/104TQ and she pulls from the bottom to the rev limiter.
But, that's just one opinion from "not a guru"; there will be others and ultimately, you will hae to make the decision. The point has been made several times that cam, heads and compression should be matched up to optimize performance from whichever cam you select.
Good luck!

Thanks djl.
I understand the reason to select parts that compliment each other. That was one of the reasons I chose the Fuel Moto power pack a couple of years ago, and have been very happy with the results. At that time I had the 54 in mind for a future cam upgrade.
I ran across a good deal on a gently used HQ 500, just have not been able to find any good dyno graphs on this cam and I have searched extensively. I like the lower lift for the stock heads since this is a daily driver and I'm not ready to dump a bunch money into it. consider it utilitarian with an additude. My main concern is not to shift the TQ curve to far right but still have more midrange. It seems that the same grind 0034 was popular in 88-95 builds and just fell out of favor.
I have made the mistake in the past to go to radical and spend to much time and money chasing #'s that the daily driving (turbos get expensive) or riding part became a chore. Trying to avoid that mistake this time.

Andrews 37 is a good choice, and would be on my short list.
Any of the cams on your list will work well, they're all similar enough. Much more important to get a good exhaust and tune than try to focus on a couple of degrees difference in duration or intake valve timing.
I'd call the tuner you're planning on using, tell him what exhaust you have, the cams you're considering, and get his opinion on which one he's had the best results with, and go with that.
Too many guys get all wrapped around the axle with cams. Really, once you've gotten it narrowed down like you have, if the cams are similar, they'll likely perform similarly once installed and tuned. You see lots of dyno chart comparsons, but that's a poor substitute for actual performance comparisons, which would require either a head-to-head face off, or a stop watch to compare time to distance or time to speed

I ended up with HQ500 from a forum member here. The cams will go in this week, called FM and the closest map they had for me was for tw37. Anybody have a map for the PCV with the HQ500, factory head pipe and jackpot dyno tuned slip-ons?

I've been going down the same road as you trying to decide. I'm going with the popular and proven SE-204's for my stock 96" based on what a local tuner has done many dyno runs with and others on these. One thing that I will mention to you, (dozens will back me), is to get the scoot put on a machine and avoid "canned maps that are close". You're shooting yourself in the foot and only doing a half assed job then. I know that route isn't cheap. There are not enough graphs, (if any), of the HQ out there to convince me that they are able to put out as much power on the left side of the bump as the 204's

I'm looking for a map to get me going, I have not found a local tuner as of now and might have to wait until the spring rally.I will more than likely end up with AT for the PCV anyhow.
What makes you think that the HQ500 will not perform well? There is not much difference between them and the 204 or s&s 510, tw37. The 510 is the closest to HQ and I know of some that swear by it in 95's with up 10 to1 comp.

I have a stock 103, started with stage one, air and 2:1 pipes and a tuner , when I added cams I chose SE255s and the map with tuner is "everything"...this thing fricken hauls. Cheaper with so
Wine else's map but I kept trying until I found it. The match between stock 103, stage one, 2:1 pipes and tuner and 255 cams is awesome.
