Which way do valve springs go?

Which way do valve springs go?

Should I change valve springs?

Replace or Reuse Valve Springs Valve springs do wear out. If you are rebuilding the engine, it is a good idea to replace the valve springs. When swapping a cam, the most important thing to avoid is valve spring coil bind. Coil bind occurs when the camshaft lifts the valve further than the spring can compress.

Are stiffer valve springs better?

Higher spring rates mean greater force on the camshaft and consequently more resistance to rotation. The flip side to this argument is that stiffer valve springs control the valves better at high speed and provide better prevention of bouncing valves, which can create more power.

What does small block Chevy valves, springs and keepers do?

Small Block Chevy Valves, Springs, Retainers & Keepers Guide In a high-performance car, the suspension system is designed for the sole purpose of maintaining tire patch contact with the road surface and improving traction.

How tall is a small block Chevy valve retainer?

For example, a typical smallblock Chevy production spring is wound at a 1.250-inch outside diameter (O.D.) and is squeezed between the retainer and the valve seat in the head at a height of around 1.750 inches. By compressing the spring slightly to attain this installed height, we can now measure the load created by the spring.

Where does the spring go on a valve head?

Installed height is the distance from the spring seat on the cylinder head to the outside spring land on the bottom of the valve spring retainer (this is the space the valve spring occupies).

What should the valve margin be on a small block Chevy?

Valve margins are another critical valve dimension and offer flow advantages for both intake and exhaust ports with specific recommendations. Most small-block intake valves prefer a wide margin of roughly 0.050-inch with a sharp edge on the chamber side of the valve. Thicker margins increase valve weight,…
