Frequently Asked Questions about automotive racing products pro series cylinder head bolt kits
Cylinder-head bolts are the connecting elements between engine block, cylinder-head gasket, and cylinder head. The bolt tightening force is an important factor for the mutual sealing of combustion chamber, lubricant and coolant channels, and the ambient air.
Partially threaded, they are rather long bolts with a diameter-to-length ratio greater than 10. The length, diameter, and shape of the head usually vary based on the engine type, its architecture, and the dimensions contemplated.
It is pretty safe to say ARP Ultra-Torque Fastener assembly lubricant is good to use on all head bolts that are not manufactured by ARP and, of course, on ARP head bolts. ARP says, "We recommend using ARP Ultra-Torque lube to ensure an even, accurate clamp load and to prevent thread galling.
Advantages of water-cooled cylinder heads: Coolant can absorb and discharge larger amounts of heat. More effective cooling can be achieved in the engine due to the cooling ducts between the cylinders and in the cylinder head.
US Bolt Head/Wrench Size
| Bolt Diameter | Head and Wrench Size |
|---|
| Hex Bolt - Lag Bolt - Square Bolt | Heavy Hex Bolt |
|---|
| 1" | 1-1/2" | 1-5/8" |
| 1-1/8" | 1-11/16" | 1-3/4" |
| 1-1/4" | 1-7/8" | 2" |
We point out to our customers that cylinder head bolts, also known as 'torque to yield' bolts or angular tightening bolts, can only be used once.
Bolt heads
Bolts use a wide variety of head designs, as do screws. These are designed to engage with the tool used to tighten them. Some bolt heads instead lock the bolt in place, so that it does not move and a tool is only needed for the nut end. Common bolt heads include hex, slotted hex washer, and socket cap.
Many everyday-use vehicles have master cylinders or other components that extend into the engine compartment. Under these specifications, head bolts allow the cylinders to be removed without removing the entire engine from the car, as is necessary with head studs.
Cylinder heads are cast from high-quality cast iron materials. During the operation of the engines, extremely high forces are acting on the cylinder head. Due to this it is necessary that the cast iron material meets the required mechanical properties and that it is temperature change resistant.
Design
| Type | Camshaft location | Intake valves location |

| Sidevalve (flathead) | Block | Block |
| Inlet over exhaust (IOE) | Block | Head |
| Overhead valve (OHV) | Block | Head |
| Overhead camshaft (OHC) | Head | Head |
The size of a bolt is determined by the diameter of the bolt's shank (separate from the bolt head). Bolt diameter is typically separated into three categories: Major diameter: The largest and most outer diameter of a bolt's shank. Pitch diameter: The diameter where the thread thickness = the space between threads.
To determine bolt diameter, measure the distance from the outer thread on one side to the outer thread on the other side. This is called major diameter. Alternatively, you can measure the bolt shank diameter. The shank is known as the body or sometimes, the shoulder.
Grade 8 bolt
For critical engine situations such as cylinder-head bolts and differential gearsets, the Grade 8 bolt is the way to go, where proper torqueing preloads the clamped joint with minimal bolt stretch.
The bolt consists of a head and a cylindrical body with screw threads along a portion of its length. The nut is the female member of the pair, having internal threads to match those of the bolt. Washers are often used to prevent loosening and crushing.
The full form of BOLT is “Binary Optimized Lite Transport.” In today's fast-paced digital age, speed is everything. Whether you're watching videos on YouTube, shopping online, or video chatting with friends across the globe, you want things to happen in a snap. That's where BOLT comes into the picture.
Automotive die casting is another cylinder head manufacturing process. In a cylinder head, die casting involves melting the material (iron/aluminum) and injecting them into a prepared mold with the cylinder head's design. The die-cast mold comes from aluminum or steel using methods such as CNC machining.
