273 Commando - Coolant leak - Cometic MLS Head Gasket

The direction from Cometic is a minimum of 50 on the Ra. It's myexperience that you really need closer to 30 for them to seal immediatey. Looking at your pictures - those are too rough. It is very common for them to leak a little if the surface or surfaces are too rough. They tend to stop after a couple heating cycles. If you don't want to do that, they can be pulled, cleaned, and copper coated before reinstallation.
