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. |

My personal engine, 102mm X 78mm, nickies with JE pistons.
Built the heads myself, 12mm plugs, 44mm X 38mm SS valves 8mm stems, new seats, dual springs , CrMo retainers, hardened keepers, shimmed, bit of exhaust porting 9mm X 8mm exhaust studs, bored to 103 register, 9.2 CR. No head gaskets, nothing really trick about the sealing surface.... I have about 20K on the engine now, my summer DD. Attached image(s) |

I also see that you unshrouded the valves quite a bit. Do you do anything special when installing your valve seats ? (Thermally) Such as warming the heads and chilling the seats before installing them ? Most of my experience has been in the Diesel world or old school Small Block Chevrolet stuff.... Thanks Keith |
