Hi gents
I would at the very least check the condition of the big end bearing and crankshaft journal for wear, ie; both measurement - dial indicator (roundness) and visual (scoring & burning).

Hi gents
On re-assembly, you will need a Gasket Set Engine Overhaul kit that can be purchased through local AROCA club sponsor.
