Guest Tom Scala Posted April 4, 2001 Share Posted April 4, 2001 I've noticed the head gaskets for 75-80 and 81-83 L6 engines are slightly different. The 75-80 gasket has many more water jacket holes in it. My question is which one would you use to mount a 81-up head to an older block? The gasket listed for the year head your using or the block? Does it even matter? I'm comparing Fel-Pro gaskets,I haven't directly compared stock Nissan ones so I'm just assuming they are different too. Thanks in advance for any info/insite.
