Headgasket thickness

I just removed the head from my 200. It looks like the previous head gasket was 2 holes or 1.48mm. I plan on having the head lightly skimmed and replacing the stem seals before putting it back on.

I have read some folks suggest putting in the 3 hole just to be on the safe side. Aside from measuring I have no way of verifying that the engine warranted the 2 hole. What is the conventional wisdom on this?

The piston protrusion above the block should dictate the head gasket thickness, there are tables in the manuals specifying the values. This measurement should be done if you have any doubt. After the head has been skimmed, the valve recess clearance must be checked, again it is specified in the manuals, get that recess wrong, and the valve and piston will eventually touch.

If you haven't done anything to the block then use the same thickness gasket. Skimming the head doesn't affect the gasket measurements. New pistons or having the block decked yes.

Ps unless it is measurably warped I would not machine the head. Clean it up and new seals
