Re: cast iron cylinder head repair?
We are in the processing of restoring a unit for a 1966 BB Vette. One head had a 2.000" long crack in the chamber. Both are being setup for "unleaded" while they're being repaired. The process involves machining for a seat insert but instead of pressing one in place, a "bead" of nickel weld is laid in the machined area. We will remachine the seat (weld) itself for the valve job. In short, the valve "seats" on the welded in "nickel" with NO insert. This is for the exhaust only. This is how many vintage heads are repaired. It's safer than trying to put an insert in with very old, thin, and extremely valuable cores that can't be replaced anymore.
This entire operation is being performed at "Champion Racing Head Service"
down in Palm Coast, Florida. It was started by a friend of ours, Al Mathon, who did ALL the cast iron welding for the original owners of the "AFX" cars when they surfaced on the scene years ago. Al has since had health problems, but appears to be well enough to oversee the guys at "Champion" to continue with welding repairs on "valuable" iron. The 2 heads we're having done are BB "square port" #858's. Thanks, Gary in N.Y.
P.S. You are welcome to contact them in Florida, the address is 13 Hargrove Grade, Palm Coast, Fl. 32137. The phone number is 386-446-4488. As I stated above, Al himself welded all the iron heads used in the original "Funny-Cars" when the manufacturers had only iron to offer. He did many 351 Cleveland's over the years.
