I have the 72cc heads on my 400 with a cam not much different than the 2802, very streetable, easy cruiser. I made 276 to the wheels with a dyno jet, I had a rusty flowmaster exhaust on it and a flex fan. I changed to a straight through magnaflow and that made a big difference on the mid to top end power. I think with a fan change I could be approaching 300. I would swap out the heads to 72cc and get a little bigger cam, then you will have a snappy engine.
