/// Another Bunch Of 273 Commando Rebuild Questions? ///

Below is a picture of #7's rod bearing.
Pretty strange wear marks. Debris or something must have got itself in somehow?

There are no ridges on the crank journal,
I'm hoping this can be polished away?

It appears I have different sets of valve springs on each head.
I have green on one side only. Anyone know what the green color valve springs are?


Piston cleaning came out good, seven more to go.....
