LT1 .030 over pistons?
I'm in the process of assembling a mild LT1 for our '96 coupe W/auto.
What I need is input on where to purchase a set of pistons and rings(.030 over).
I want to retain the approx. same CR. I believe that I want "hypereutectic" style pistons. There will not be any power adders such as nitroxide, or super charging. Also I would like input on the recommended camshaft. I have long tube headers, ported LT1 heads, and stock converter. I have a "LT4 Hot Cam", but I'm conserned about it working with a stock or near stock converter. I believe that I may need to select another camshaft. This Vette is a weekend cruiser and my wife drives it some.
Thank you!

On the rings:
there are sets that are "pre-gapped" and there are sets that need to be "filed-to-fit".
If you do get the "pre-gapped", check them in the cylinder bores anyway. No need to skip this important step. Takes a half hour at most
Sometimes they are off by quite abit. Have seen this a number of times.
If gap is too tight, you can always file them, but if too wide, consider sending them back and getting ones to your satisfaction.

For my 383 LT1 rebuild I wanted to achive a mild build like yourself.. I am very pleased with the hyperutectic pistons I selected that were manufactured by Keith Black (KB).. They are the Silverlight (or something like that) line and work great.. they offer the stock 10.4:1 ratio and the 10.8:1 ratio pistons (which are the ones I selected).
I have a cam similar to the LT4 hot cam, stock heads, stock exhaust (exp. no cats) and a stock converter..

If you want something a little lighter and stronger, SRPs are another alternative. Here's a pic of the SRPs in my engine:
