What is the process of determining what head gasket thickness is needed ? I recently purchased a built short block and I’m having the heads resurfaced. The pistons selected specify a compression ration of 10.6:1.
Headgasket will also have an impact in Compression Ratio, because the area on the circle diameter of the gasket by the height (thickness of it) will give you the volume of the headgasket. To know the static CR you would need to know: the volume of the cylinder (piston from BDC to TDC), the volume of the combustion chamber in the head and the volume of the headgasket diameter and thickness. This is supposing the pistons are flat and get to the top face of the block.
Remember that head gaskets will squish a bit after you torque the bolts, so its kinda difficult to measure a gasket. Check the manufacture "diameter and thickness on the gasket characteristics".
Thanks. I will also ask the engine builder for input.
