I'm aware of the 4.000" bore size and the question of whether or not the gasket could possibly cause pre-ignition has never been fully answered or explained to me. If it bothers you, use the GM 14096405 with a 4.100" bore, same thickness. It's the gasket that GM used on the ZZ motors with aluminum heads.
