Help ID these jugs

They've been in a box in the garage for years and I can't remember what they are or how I ended up with them. They are stamped 84 std and have wrist pins. Any idea what they are and their value? I'm thinning out my stuff. thx

Those appear to be either 2.2T or 2.4T pistons and cylinders. There should be a casting number inside the piston that will begin with 84P. The cylinders look to be 84 mm cast iron. They will have a casting number near base.

Pelican shows those head gaskets are for 1970-73 911. 2.2L - 2.4L as Tom says.

Thanks - The jugs are painted black outside, so I doubt they're Mahle. I'll take a look at the skirts.

Check the bores with a magnet; they might be some kind of Biral-type cylinder. QSC maybe?

I doubt QSC.

The clips aren't what QSC uses and they don't machine the groove for the CE ring on top last I checked.
