What type of riding do you do and where, where are your current shift points (rpm), so you ride more solo or 2-up, whats your budget, are you doing the work or farming out to a shop? Too many questions based on your initial post to suggest anything other than ride what you have and then make a guess later...

I have had 509G's in my 03 bagger for 8K miles, with a Thundermax tuner and O2 sensors
Once it goes above 2500 RPM's it scoots right along, great for highway and passing as it really comes alive at over 2800 to 5000,
It is a good broad power band cam for the TC88, where I am told the 510 is a tad peaky and only likes high rev's
and you are not going to have to worry about coil bind in the heads.

Certainly not knocking the S&S 509 cams... I know nothing about them....
Just for variety sake, my go to cam for an OEM 88' has always been an Andrews 21 cam..... They come on about 1700 rpms and go strong up to about 5K rpms... good bolt-in, mid range cam... where most people ride...
