Rip Chain for 660 ?

[HansFranz]

I want to build a woodworking workbench but can't find decent lumber for the 2' x 7' x 3-6" top, so I plan to cut slab(s) from a dead tree (I think I have a dead white oak or loblolly pine that will work), then joint and glue them up if need be.

Don't have an Alaskan mill, but plan to nail a board to the tree as a guide to get a planar surface, then turn it and repeat to square it up and get it down to manageable size to bring home and work on...

Can anyone recommend a good ripping chain to use for this on my 660 with 28" bar?
The bar uses .050" chain 3/8" and IIRC 91 DL.
If I'm lucky, I think there's a WO that's been down 10+ yrs., so assume it'll be dry and hard stuff.

I googled around for a while, but kind of got lost. Thanks for any help.

If it had been 3/8 058 I could have made you a loop ripping 10 degree semi chisel to try. From these 2 100' rolls I got on trade years back. 1 was ripping and 1 full skip FC.
I was just going to file it back to normal if that need ever comes.
