Anyone here ever have their pistons machined?

Anyone here ever have their pistons machined?

I have told you TIME AND TIME AGAIN. You need to DISASSEMBLE the distributor. You need to use the Mallory keys to limit the mechanical advance. The keys are numbered according to the amount of advance. I don't know how to make it any plainer. Yet, you keep wanting to go back to major engine work to try and solve your problem. I HAVE stepped up to the plate SEVERAL TIMES and told you what to do and how to do it. You have REFUSED to listen. I don't know what else to do. If you lived close by, I would come by and fix you up in less than an hour. It's not hard to do, you do have to follow instructions though.

I have not made up my mind on anything yet. I like to know what options are available.
For the record:
What do you think I've been doing? I have asked numerous times about the ignition curve and the most helpful suggestions have been...you need to delay full advance until 3500.....
Great. Now how in the world am I to do that? Stiffer springs? NOBODY has stepped up to suggest what springs, where to get them or anything else on that matter. I am dealing with an engine that knocks at anything over 25 degrees of total timing. It USED to detonate at 31 with the old cam, NOW it knocks long before that. I mentioned in the other thread that the Lunati cam swap resulted in worse detonation than I had with the 509 cam. This was with 91 octane.
It may be annoying for you to read all these threads on the same problem. Despite some members opinions, I am not waiting around for people to approve my own ideas or what I have already decided. I'm not co-dependant to the point where I need validation of what I do. I ask when I truly do not know.
