Just stick with a mild cam from Straub or Tooley and a set of Tooley springs. In fact they sell a whole kit that would come with everything you would need. As far as trunions go, it's highly recommended but not required. Even if you didn't have an aftermarket cam, they are prone to breaking down prematurely. So the straub reunion upgrade is the way to go there.
