Sounds like a decent exhaust, but I would use a dual pattern cam anyway to help it breath. I thought it might have been stroked, but since it's not, the tighter LSA wouldn't help that much. I would look at the Voodoo 60104 cam for it. It's on a 110 LSA with 4 degrees advance built in. It will work with the converter you have also because of the size engine and vehicle weight.
