Brent's 920 Norton with FullAuto Head

I finally got the 920 Norton back together and I am very pleased with the results.

I am very happy with the FullAuto head. I definitely have improved mid-range torque and the motor starts and idles better. In part, this was expected due to returning to stock intake valve diameter. I also suspect the Fullauto improved exhaust port geometry plays a part as well.

Also, I am very happy with the Total Seal ‘gas ported’ rings. The exhaust gas blowby issue is now non-existent.

All in all, I feel this is the best build yet!!
