[Fot] TR sleeve protrusion .011

[Ponostyle]

Solid copper and brass doesn’t really creep much in compression. And if it did, in this case the gasket is bounded on the edges with not many places to creep to.

> Changing the figure 8 gasket thickness does sound like the easiest and most precise solution.  Several others have made the same suggestion to use brass or copper shim stock. I am leery of creep in brass or copper. What is the experience you all have had? Does the creep take a set after a while or do you need to continually retorque the head?  Is there a similar issue with solid copper head gaskets?

You can get brass shim stock from local hardware store or McMaster Carr and cut out with scissors / snips.  I do separate O shapes, the siamesed cylinders don't really need the gasket combined into a fig 8 one.

>>> I am trying to build an engine quickly (avoiding machine shop delays) and have a block with billet crank and Chris Marx seal installed. It has been decked already. Also line bored and cam bearings and cam installed and timed. I want to know if I can assemble this with confidence or if I am asking for trouble?  I don’t anticipate problems with oil or water sealing as I will use Hylomar on a .020” steel head gasket with the raised corrugating around the oil and water galleys.
