Dart head identification is based on the manufacturer’s information in the stamping part. Therefore, it’s essential to identify exactly what you need to know about this information.
The following article will show you how to identify dart heads and provide information related to dart production heads. Keep reading for more info!
Dart Head Identification – Detail Instruction
High-end aftermarket heads are easily distinguished by end stamping position, which can be used for easy identification.
In this position are two sets of numbers, one identifying the head type when researched on Dart’s paper or Dart engine catalog.
The opposite set of numerals will represent the day, year, and rotational shift that was manufactured.
How do you determine the stamping position at each end?
The stamping part of a dart block is typically displayed on the front of the block and should be the first point of reference when determining the type of block you have.
A letter followed by a series of numbers can be found here:
The first letter of the block’s stamp will tell you the manufacturer and the approximate layout parameters and dimensions of the engine when it was first produced.
At the same time, the size of the complete block or the substance making up the block (cast iron or aluminum, for example) is determined by this letter.
The last digit provides additional information for pinpointing the precise block. These are the only numbers in the block, and they are stamped directly onto the front cover.
Cap stamping facilitates user identification of blocks and ensures critical caps consistently correspond to your blocks.
The front of most dart blocks features a logo or other identifying.
However, these are tricky to place in the Dart category; I recommend contacting Dart’s IT department to request additional identifying information.
The date code is often shown opposite the big chief cylinder head selection and consists of three digits followed by two pairs of integers and a separate number.
Example: Let’s say your production date is 352-space-13-space-1.
Through this number, you will know that the competitive cylinder heads selection was manufactured on the 249th day of 2013, and the last unique number will also tell you the change of the date it was manufactured.

FAQs
Where Are Dart Heads Cast?
Casting heads and blocks are made from raw castings at a separate facility in Melvindale, Michigan, which has enormous CNC machining facilities.
Dart Machinery is now widely regarded as the go-to manufacturer for high-performance automotive parts.
What Heads Should I Put On My Chevy 350?
A standard 350 Chevy street engine develops 400 to 450 horsepower, making it suitable for a pair of production heads with Intake Port 180cc or 185cc intake runner versions.
It’s likely safe to use the 200cc intake runner version on a 383 stroker. However, adding a high-flow head with 220cc runners to a stock-ish 350 wouldn’t be a good idea.
Conclusion
Dart heads identification is a relatively easy task. First, you need to pay attention to the end stamping position, where the sets of numbers are.
These sets of numbers show identification information and help you know the production time of the dart head.
However, the best way to correctly identify the dart high performance heads is to contact Dart’s IT department to request additional identification information.
I hope the above information will be helpful to you. Thanks for your attention!
