Why not get it from Group K?

They are very good builder guys but not very confortable with export

You need to measure the bottom of the bb850 sleeve and mill the crankcase to that size. No other porting is needed unless you want to
I built a bb850, it's not difficult.
Used cr500 pistons which require a shim under the cylinder.
I don't know about groupK pistons

You just need a base gasket?

Use a stock base gasket and trim the part that goes around the larger sleeve.

It cuts easily with scissors or a utility knife. Set the gasket on the case and press on it at the edge that needs to be trimmed with a slightly dirty thumb and it will give you a nice line to trim on.

Do you have a spare base gasket that fits? When I run into odd gaskets I toss them on a scanner and get shape off of that. I have a silhouette cutter (different brand of cricut) that I can use to cut out whatever gaskets that I need. A vinyl sign cutter would also work, but I was able to pick up the silhouette cheap cause all the craft people want the newest fancy cutter. You can also make a template for the gasket by cutting thin masking tape to shape and then scanning it.
