Kabadi,
Found the following at British Only. They also had 10.5:1, which I think should be avoided, unless you are planning on racing. I'm not sure what a 9.5:1 profile looks like, but suspect they are really 9:1. I would want to know before I bought them. I also don't know anything about Mondial pistons. Others might. Finally, are you sure that machining/honing out maybe less than 0.010 will get rid of all the pits?
