Bearing clearance was a bit much on rods and mains.

Had to buy two sets of bearings. One standard set and one with .001" less clearance.

For example shooting for .003" clearance on the mains. It measured out at .0035"

To correct this I install a standard bearing half and a .001" tight bearing half in each hole. Brings the clearances right where I wanted them.

Now what to do with the two broken bearing sets?

Oily workbench mess now in the engine. Perfect .005" in the hole as planned.

Using custom thickness Cometic head gaskets.

Two outer layers are coated and standard thickness. Inner layer sets the overall thickness.

Check head gasket fit against the head.
Make sure everything lines up.
