'Pop's Engine' another 440 on the dyno.

I'll post some dyno results as soon as I get some free time. But for right now we got roughly the same horsepower and torque increase from just going to a 1.81 exhaust valve w/ the increase of flow as we did when we changed to the M1 intake and the 2" spacer. Again, we went back to the Performer RPM intake and added 1.81 exhaust valves to the 346 heads and the increase was about the same as using the M1 intake with the 2" spacer.
