Re: Help for date code on BBC heads
Those heads were used 69 and 70. One thing you guys missed is the spark plug hole size. ALL 1970 model year heads used the small tapered seat spark plug and all 69 models used the larger flat washer type speark plug. the spark plug hole will tell you which year they are.
The pic looks like L 1 1969 to me, check spark plug holes for tapered seat machining
