My opinion
Cut it. I don't know the reason for the bevel unless there is a clearance issue in the block at the combustion chamber or different porting from one block to another. If you don't cut it you would have more compression on that hole or worse, interference. You can take it to a machine shop or you can take out the file and do it yourself. You will get it plenty close enough just don't use anything that will cause a build up of heat and make sure it is nice and smooth like the rest of the piston.
I responded to this thread earlier that the tower of power likes to spin free but was wrong on the rpm. Some of the 150 hp inlines like to spin up to 6800 to 7000 but I read somewhere that the 90 and 115 like fewer like 5800 to 6200 max. The fact that it lived as long as it did is proof that you must have been doing it right all along.
How about the tools, were you successful in locating the tools you needed?
