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. |

So, it sounds like I need to consider not using head gaskets. I researched this some time ago, but, it seems that the consensus here is not to use them. Maybe somebody could post the process that needs to be performed to leave them out? Can this be done by a "garage mechanic" like myself? (IMG:style_emoticons/default/biggrin.gif) |

(IMG:style_emoticons/default/biggrin.gif) For those of us watching from the side lines, I think this captures the question. If you buy a typical set of cylinders and don't have access to have the top surface re-machined, and you heads are freshly done by a competent (but probably not a specialist) machine shop, are you more or less likely to have issues with or without head gaskets. And if you are leaving the head gaskets out, do you have any additional prep required?? To roll all the way back to the OP, if his engine was built with head gaskets, what is the chance he can reseat the heads without them? How much risk is there due to the slight increase in compression and/or the slight decrease in effective deck height? |
