I see now that I read it again, it has headers on it .. duh, sorry.

I would look for one arching through the header. Another consideration would be a restriction in the old exhaust setup. For example if you had it running slightly more lean/rich to compensate for the other setup .. now that you have headers and less restrictive exhaust the engine can handle a little more timing and even a slight carb adjustment.
