Complete Rotational Assembly Balancing
ARP Head Studs
Using studs will make it much easier to assemble an engine (especially a racing powerplant which must be serviced frequently and quickly!) with the cylinder head and gasket assured of proper alignment. Studs also provide more accurate and consistent torque loading. Here’s why. When you use bolts to secure the head, the fastener is being “twisted” while it’s being torqued to the proper reading. Accordingly, the bolt is reacting to two different forces simultaneously. A stud should be installed in a “relaxed” mode – never crank it in tightly using a jammed nut. If everything is right, the stud should be installed finger tight. Then, when applying torque to the nut, the stud will stretch only on the vertical axis. Remember, an undercut shorter stud will have a rate similar to a longer, standard shank stud. This provides a more even clamping force on the head. Because the head gasket will compress upon initial torqueing, make sure studs and bolts are re-torqued after the engine has been run.

Balanced Rational Assembly
The basic idea behind engine balancing is to equalize reciprocating forces as much as possible and to make sure all rotating mass (the crankshaft and the lower half of the connecting rods) are in balance so the crank spins smoothly about its center axis. When a rotating object such as a crankshaft, flywheel or tire is out of balance, it wobbles because its center of mass does not align with its axis of rotation. The heavy spot wants to pull the object off-center as it rotates. The centripetal force generated by the imbalance multiplies exponentially with the speed of rotation (doubling the speed quadruples the force), creating a shake or vibration. Balancing a rotating object requires placing it in a spin balancer so the heavy spot can be pinpointed. In the case of a tire balancer, a weight equal to the imbalance is then attached to the wheel rim opposite the heavy spot to equalize the forces. With a crankshaft or flywheel, it’s much easier to lighten the heavy spot than it is to add weight, so the balancer pinpoints the heavy spot so a hole or holes can be drilled into the component to reduce the imbalance. It usually takes several spins and corrections before the balance is achieved. If the mass of the counterweight equals the weight of the upper half of the rod, piston, wrist pin and rings, the forces will be balanced and the engine will run smoothly.
New Gudes and Hardened Seats
Harden Seats have a better heat dissipation , longer life and prevents cracks from spreading throughout the head. We use high grade alloy matter in all our builds. New Guides installed. Core drill reemed to remove integrated guides that was cast. We install the cast iron guild because it contains graphite which last substantially longer than a spiral brass sleeve. All guides are honed and NOT reemed . This allows for oil retention in guide which aides in longer life.
As customizable as YOU choose
Many Builders have an arsenal of about 3 different options each engine. We are unique in the fact that we let our customers choose however custom they want it to be. Sure we have our standards (The Daily Driver, and the Workhorse ) but we pride our selves on giving our customer what they want. Many times we get calls from Customer who are not sure. Our Job as the Manufacture is to sell you exactly what you need.
