I just pulled the rocker assembly off my original MGB 12H 1326 cylinder head and began to clean up the mess. Everything looks great and using my crude method of checking warpage the head looks to be nice and flat with less than .002 warpage. Not bad. The rocker assembly also appears to be in great shape. I expect these were all redone at the 98,000 mile rebuild so they only have about 37,000 miles at present. Fortunately the work appears to be better quality than the main engine that was a bit of a mess.
Here’s what’s cool. The MGB cylinder head is 50 years old this month. It was manufactured on November 2, 1966. Happy birthday! Next up is the engine block which turns 50 in January 1967. I’m guessing the 1967 MGB GT was actually produced in February 1967 although I have yet to confirm this. It was purchased new at Peter Satori Ltd. in Pasadena, California in January 1968.
