J head question

X heads never had the 915 casting. The last 3 were 894. Look at your picture and you can see the casting #. The 915 "J" heads came both ways. 1.88 and 2.02. The 360 casting on the head doesn't mean that they are 360 heads since the 360 engine came out in 73 for the cars. It's just a casting number, not an engine designation.
