I was told at my local dealer that genuine headgaskets were NLA. May or may not be true.
The guy at my local head shop said ACL monotorque was the go, rather than the other ACL (the one you got by the looks of it) I think monotorque uses blue sealant and the bad one uses red sealant

yea i got the Lseries so might be able to find a genuine one still. Are the monotorque ones the ones that need retightning? Im only running 8psi still so im hoping it may have been a combination of #### gasket and overheating, bottom end looks fine/the same other than a non-carbon caked piston in cyl 1 from the water. I have never heard it ping either, ive heard of people running up to 30psi without Oringing etc.

Quote: Are the monotorque ones the ones that need retightning? monotorque = one torque, so Id say you only tighten them down once.

it has instructions on the packet on how to install it
with L series you will only need to torque it once, in sequence so really 2 torques
but as the head bolts dont stretch you dont need to run it then retighten
just torque all the bolts to 65nm then to 83nm and it should be good

A lot of new engines use some sort of stretch head bolts that have to be replaced when you take the head off. But Datsun weren't up for that sort of crazyness!
