Perkins 4.203 liners came in an overhaul kit. Do they need bored?

[somanytractors]

I'm rebuilding a perkins 4.203 in an mf65.
The kit comes with liners and I planned on replacing them.
While looking around I seen several posts saying most liners need to be bored after installation.
How can I tell if these are supposed to be bored after installation or not?
They came in a kit with the pistons inside the liners. They are pretty thin and are already honed so I would think they're finished and shouldn't need boring.

The kit I got is at IN-FRAME ENGINE OVERHAUL KIT FOR MASSEY FERGUSON- PERKINS AD4.203 65 165 255 30 | eBay

I got one liner out and I know how to put them in, I'm just a little confused over the boring thing.
Any guidance is greatly appreciated.

Thanks
John

It’s been multiple decades since I worked with dry liners and they were IH not Massey.

However, I think all dry liners have to be honed after installation.

After installing the liners you could take the block with installed liners and pistons to a machine shop to confirm proper fit. Don't forget the end gap on your rings.
