Big Block B Heads?????
I just found the B code on my heads can you tell me what all the letters mean and what are B heads. I seem to have a ticking some times from the front left side but it runs good AND DOESN'T SMOKE yea 425CI 1966 Delta 88 2dr ht. thanks for the info WEBBISH

b heads i believe stand for body style of car. the large body olds are known as "b" body and the cutlass are known as "a" body. as far as your ticking. sounds like you have a lifter sticking. chris

Incorrect... the B is like a casting number. Different years used different letter codes and in come cases different performance levels got different letters. If they are on a big car you should have small valve B heads. A 66 442 used the B head with the more desireable big valves.

Olds big block heads use letter codes like B, C, D, etc. Small block heads use number codes like 5, 5A, 6 etc. If you hear a ticking sound intermittently from one side it is probably valve train wear due to age. If it does not affect the drive ability of the car just let it go until you decide to do some engine work on it. Rebuilding the heads may help but with an engine that old a complete rebuild is probably what you need sooner or later.

If you are driving a Delta 88 then B heads will be fine for a rebuild unless you want to go "all out." The BB heads you want to stay away from are the J heads. Those weren't available until the 70s though.

Learning every day I guess the correct terminalogy would be all original engine trans and rear end all came in the car from the factory nothing has ever been changed or removed. Better!!!
