Inliners International Forums General Discussion Vortec 4200 Thicker than stock exhaust manifold gasket

Just curious if one exists for an 02 4200. Everything seems straight but I want to be sure I don't have any leaks for using a wideband.

The #1 and #6 have loosened a few times so if I pull the manifold to check for a burned gasket, I want to put one back that has a little more meat in it. There's a faint tick or tap which is why I want to check.

check the manifold for cracks.. I've only seen the stock thickness gasket.
