Im thinking of getting my 261 rebuilt before I install it. Nothing fancy, but it will need to be bored, the cylinders are egg shaped. I checked with a few old time parts stores, and other sources for recommendations, and got nothing solid. A search on the HAMB didn't turn up anything. So I'm reaching out for shops you've used, and would recommend to get your stovebolt rebuilt. I've looked at a few, but it's good to hear who you've had good results from. Thanks
