Just noticed Cylinder Works offers a replacement head for the YZ250 that appears cast and very similar to the stock head.

Unfortunately, info is pretty skimpy as far as compression, squish, etc. Wondering if anyone has any info on this?

“Replacement head”. My guess is it’s identical to the oem head. If yours is damaged this is the one to buy if you’d want a brand new head

Yeah, that's what I basically figured. The issue is, it fits 99-2017 and the compression changed a few times in there. So is it the same as a stock 2005 or stock 2016?? Also, the stock YZ250 squish is a little suspect so it would have made sense if they spec'd it with an improved squish shape.
