Nice pic Ron. Are you useing a stock valve with the shoulder and cutting that shoulder off and undercutting under the head? I oftened wondered if these were 2 piece valves. If so will thay stay together? Walt

those look nice..........im confused now? in JOE ABBIN's blown flathead (his first book). his flow charts show the 1.6 flowing better at low rpm?

Walt I took these pictures along time ago and yes i understand all these exhaust valve are two piece. Not sure about the intakes. I was ay TRW and wtched this operation it's called friction welding. I just run that carbide down the stem and backing out at a 20 deg angle leaving about .90" for a seat. This and the combustion chamber work was included in all my engines, Not sure how well it worked, but most are still running.
