They 1341 pistons? If so then you will be fine - lots of us are running 1341cc without issues.

Hey thanks for the reply

Yeah there are 1341

Just thought the corrosion on the one pictured was excessive, giving little sealing area?

I would:

- measure depth of pitting
- calculate CR with block decked to remove pitting
- if too high use stock composite gasket (not 6n metal item)
- Swear, remove pistons, strip block and get it machined.

You could do the opposite and weld it up and surface grind the face, but I'd have thought a new block would be cheaper.
