Default Re: Manifold Gland Rings

We could possibly distinguish here between "are gland rings needed" and "are gland rings helpful." My understanding is that they're helpful in preventing manifold drop and damage to the gasket from high-temp gases. However, if it is difficult or impractical to procure gland rings that are the correct size, or if the manifold has previously been resurfaced, such that there is no longer sufficient depth to permit the rings to be installed correctly, the benefit provided by the rings may not be enough to justify the cost of modifying the manifold/block or hunting for rings that are the correct size.
