Looks like that's your tapping though lol.
Well when I say winter it was still 20 degrees today

A lot of people suffered big end failure after belt snapping but there was no conclusive evidence they were linked. Some were going a matter of weeks after, some 50k after.
Personally if it were me and i had the head off for a rebuild, id have the rods out, do the rings and big ends whilst i was there. Parts arent exactly expensive in the grand scheme of things and its easy to do in the state its in.
This is exactly the thinking, When you stop and think about it.
The timing was spot on and #3 has rubbing in the cutouts and touched valves but only on this cylinder and only on the exhaust.
Would you not expect to see this or at least some marking on all 4 cylinders.?
The only other way valves are going to rub a single piston is either little end or big end clearance i would have thought.
The head is pretty close to it's last skim too.
Bigends, mains and thrusts are on order but I'm still deciding if I'll do the rings, the engine has been done before at some stage as the hone marks are still quite visible.
Of course if #3 bigend/littleend is gone then that changes the plan.
