mine used to melt the top left corner when was being mapped on the RR, but since i've used the copper ones they are fine.

The bottom stud nearest the bulkhead on the manifold became weak as the gasket blew there twice and now its fallen out dont know why this is such a common problem with these heads. Even after i helicoiled 3 of them and used loctite on the threads i still have to nip them up every few days

[adzs12]

Just been on the phone to ferriday and im being sent some new gaskets that the guys been testing for a while now. Apparently there 6 mm thick and have been tested to high temps that will stop the heat going back into the cylinder head, so il try them out as there free of charge nad see what happens. If there crap il use the copper ones but i dont mind my manifold being the lab rat for some new and maybe improved gaskets

sound job

Shaun did the guy mention these new gaskets to you? Or did you just decline the offer of trial?

6mm seems very thick. Hopefully the nuts can go fully onto the studs (sounds very gay that)

i don't think he was doing them when i had my copper ones made, hope they work well matey, if only there where some head bolts out there from ARP, i'd try one of there copper head gaskets and wind the boost up to about 32psi.

I thought this straight away but im sure theres about 5-6mm thread left after the nuts have gone on using the standard gasket so trial and error is all i can do

should be very very easy to get ARP's for an ET it's only a standard m10 thread, not like the M11 on the DET

YEP this is true. Arp will have some on the shelf if you specify the thread rather than the car type.

The gaskets sound pretty interesting Adz. Post a few pics and a review up if you can mate. As you say. there thick to reduce heat transfer back to the head from the manifold which eventually weakens the ali. . Who cares if there thick if they are uprated. I used to blow mine on my et. I guess were just to hardcore for Nissan,
