Cometic Nissan VG30DE/VG30DETT Top End Gasket Kit - 90mm Bore - .045in MLS Cylinder Head Gasket

If you're rebuilding the top end of your 1990-1996 Nissan 300ZX or 1993-1997 Infiniti J30, this Cometic StreetPro Top End Gasket Kit is a solid option. It bundles all the essential gaskets and seals you'll need to get your VG30DE or VG30DETT engine back together with confidence. The kit centers around a Multi-Layer Steel (MLS) head gasket, measuring .045 inches thick with a 90mm bore, which is crucial for sealing the combustion chambers effectively.

Cometic uses a variety of quality gasket materials in their StreetPro kits, including MLS, AFM, Aramid Fiber, and Armor Clad, depending on the specific application. This ensures each gasket in the kit is well-suited for its job, whether it's sealing oil passages, coolant, or the high pressures within the cylinders. The .045 inch thickness of the head gasket is a common choice for stock or mildly modified engines, providing a good balance of sealing performance and compression ratio.

This kit is designed to cover the top end of your engine, meaning you'll find the necessary components for the cylinder heads, intake manifold, and valve covers. Having all these parts in one package saves you time and ensures you don't miss any small, but critical, seals during your rebuild.
