What will adding 4 degrees of exhaust duration do?
I have an F13 (230/232) 111+1 cam and have to take it out to send it to Futral. I'm thinking about just buying another cam. I'm thinking about a 230/236 112+2 cam to replace it with. Seeing that they have the same intake duration and ICL, what will adding just 4* of exhaust duration do as far as power and where it peaks?

It pretty much won't do anything. Your only changing your IVC by 1/2 a degree and overlap will stay exactly the same. The intake valve closing is what determines your peak, and your not changing it. The longer duration might help if you have a poor exaust port/system, but that's likley going to be neglagent.
