Help I.D. Head Gasket

Featured Replies

It is from a 280zx w N42 Block

 

Diameter is 89.4mm

Squished height is 1.04mm

 

I can faintly see 12 NR Z embosed between the timing chain hole and cylinder #1

 

The oil seal is copper. Sealing rings are steel.

 

Seems like some faint baby blue colours

 

I am guessing NRZ is Nippon-Reinz?
