Serial Number Identification

BRODIX started numbering small block heads in April of 1979; an alpha-numeric system was started with A 1 in August of 1979. Big block heads started with numbers only in April of 1984, but changed to alpha-numeric starting with BB 1 in August of 1984. The stamping is usually located on the end of the casting above the accessory bolt area just below the valve cover rail. We have stamped some heads on the exhaust side of the head as well. The numbering system only identifies the casting model and the year the head was made.
We will only be able to give you the casting model and the year the head was made. Due to the nature of the performance industry, the need to modify parts to fit a particular application, and the long life expectancy of BRODIX heads, there are too many variables to consider when giving information on heads that have been modified after leaving our facility.

Please use all caps and no spaces on your serial number. (Ex: JI895)
