Generation IV Internal Engine - lq4 bore size ?

I just got off the phone with diamond pistons and they told me they had pistons for my set up in 4.060 and 4.065. I thought 4.030 was as far as you wanted to bore out an lq4 6.0L iron block. Would you guys bore it out to 4.060 or 4.065?

There are shops out there going .090 over with the iron 6.0 blocks. It's a matter of finding the right block that sonic tests o.k. Wall thickness wise. I'm going .065 with my ly6.

I will be boring it out further then to 4.060 so I can get off the shelf pistons for it.
