THE 103 KIT was already installed when I bought the bike used it had 8500 miles on it. It now has 26,000 on it and I don't know what has all been done but i think it is all stock except for the 103 and air cleaner I had a power commander put on it. woods tw555 have been recommended,. Wondering if this is a good choice? not really looking for a tire smoker just want to get up the hill
just to let you know, if you go with the woods you can't use the original push rods...you have to go with adjustable ones...

It's all good. There were a few lengthy and overthought cam threads recently that were like arguing religion and politics.

You want to get "up the hill" with your set up? SE255 would work. I have a 103 with rineharts and heavy breather running a S&S 551. I reused the stock pushrods and all is well. My set up will definitely get you "up the hill" as would the SE255. You appear to need a torque cam. You can tell that everyone has their favorite. Any good torque cam should get you what you want.

When you did the big bore kit, did you change to a mls head gasket? Did you do a deck check or cc your chambers? With the heads off, I would be looking to equalize the chambers and bump the compression just a little, which can have a significant impact on which cams you will choose. I would not assume you have the same compression as an otherwise stock 103er.
Once you have the data, you can choose from a variety of cams that will work. Getting the compression right for the selected cams is important. Much of the performance gain from installing a set of cams with the correct compression can be attributed to the increase in compression, not the cams themselves.
