I need to remove the heads off of a newly rebuilt engine (4-cylinder) I built (never run). They have already been torqued. Are the head gaskets and gasket between the cylinder and block, compression gaskets that should be thrown away (i.e., replaced with new one) after I untorque the heads?
The head gaskets will be easy to replace. But I'd have to pull the cylinders to replace the ones between them and the block. |

^well said. my experience would lead me to lap the cylinders into the head with grinding paste to get a uniform surface. on a 1930's norton 500 single, easy to do without upsetting the cylinders and rings. on a type IV, not so much as you would have to remove cylinders and lap them into the head to get a uniform surface. i use the gasket because it is easier to get a tight mating surface without disturbing the ringland. on a blueprinted, heavily modified engine with lots of aftermarket components and custom machine work, i can see it. a stock street motor not so much.
