Advice on my "stock" 340 build

I built a similar engine last year. It has only run on the test stand. I too wanted to keep it fairly stock and went with the Oregon 68 4 speed cam installed 2 degrees advanced with stock rocker gear. The stock heads were rebuilt with nail head valves which reduced the combustion chamber volume down to 63 cc for 9.75:1 compression. I didn't have a stock manifold or carb so went with the Eddy RPM (non air gap) and Eddy 650AVS. Everything else is stock except ARP rod bolts. I have a 4 speed with the low 1st gear, 3:55s and stock 14" rear tire size. I hope it works out :)
