Silv-o-Lite is just Silv-o-Lite, they are the makers(United Engine and Machine Co.) of these pistons, nobody but them uses that name. They are however, the same company that makes the Keith Black Hyperuetectic pistons, but the Silv-o-Lite hyperuetectic pistons are the budget standard rebuilder and claimer racing line, different then the KB's performance line.

The Silv-o-Lites use a standard ring gap, it is only the KB hypers with their higher ring position on the piston that have a special larger gap requirement due to being closer to the top gets them more heat, thus more heat expansion room is needed.

Use the formula you have always used.
