Pretty hard to tell from those pics... & even with good pic's it can be hard to say.
If the plating isn't obviously damaged I'd be inclined to have a go at cleaning it up. If that works smooth over any irregularities in the ports, re champher them & see how it runs with a new pistin & rings

Plating is broken.
Deep scratches and only alum. body around intake port. Without cromeplating...

Be sure to have 272 intake spacer,bolts,etc { different from your 162 }before buying your cylinder.

I have intake spacer for 272, and need decompressor - this not difficult to buy

Go with a 266 style cylinder. Only 162/630 and 266 cylinders will fit under your top cover without spark plug interference. It also uses the same intake block you already have.

If you have access to the internet- you have access to Husqvarna parts- as does anyone in the World.
It all comes down to what you are willing to spend.

May well be nikasil coated- but nothing to say that coating will stick to the base material, is of similar quality, or similar finish.

That's an OEM 268 that has been swapped to a 266/61 style filter. The 162 top cover doesn't even get down far enough to rub on the filter screws like it does on a 266.
Whoever said you didn't need a top cover change for a 268 or 272 top end gave you bad information.
A mid/late 84 266/61 cover with the bigger spark plug bump will clear, a 162 or 162 based 61 cover does not.


Here you can see the difference between the early and late 266/61 covers. The ones with the flat area in the top of the spark plug bump clear a 268 or 272 top end, the early ones are similar to the 162 cover in that area, and do not clear.
