Installing Nickel Alloy Seats in Pan Heads
This video demonstrates the installation of nickel alloy valve seats in Panhead engines manufactured between 1948 and 1965. The presenter showcases two different machines used for this process: a milling machine that cuts out the old seat for a precise interference fit, and a Sunnen headmaster machine. Both tools achieve the same objective in preparing the cylinder head for new valve seats. The description also includes a link to purchase shop t-shirts from Dragonman's.
