I checked my ARP torque after ~20 heat cycles and they had lost a little torque. There is a lot at play when you have that many items stacking up when cold, then subjecting them to multiple heat cycles. I suspect some internal stresses exist when you first mount the cylinder head due to very small misalignments and fasteners causing preloads in different items. After some heat cycling these internal stresses relocate or cause the component to relax and causes a slight torque loss. Just a hypothesis.
They dont need to be babysat, but checking them after some heat cycles is a requirement for me.

They have an 87mm cut ring gasket for ya! Everyone is raving about them on BF.C
But yes, you can O ring it still, but that would take a trip to the machine shop. Cut ring is faster/easier.
I have a call into them. Going to ask if they have different thicknesses IF I have to resurface the head.

Do you also have to take your turbo off to get your valve cover off?
I suppose if you are taking your head off it is coming off anyway. -

None broken. No tools used except for an 11mm and a Cresent Wrench.

The head gasket replacement journey.
Keeping organized.
Too much wear?
I can feel this one with my fingernail.
Now I just need to disconnect my downpipe and remove the ARP head bolts and see the carnage.

Question. If some show some wear do I need new caps, carrier and cam? I feel one journal with my fingernail...

It is doubtful that you would have much success with other bearing caps since they are machined as a unit with the head and even running the caps that are mounted in the wrong location (originally machined for exhaust cam bearing #3 but using it on intake cam bearing #3) can be problematic
When I was 17 I found this out the hard way when using a bearing cap from another engine and not being able to turn the engine over even with the bearing cap well under-torqued at 15ft-lb.
I would scotch brite the scuff lightly to help knock down the edge a little and just not worry about it remembering that even at 7000 rpm your cams are only turning 3500 and arent under nearly the same load as the bearings on the crank.

Man that is nasty! Looks like a milkshake that I would not be interested in drinking!

It wasn't all that bad from other pictures I've seen.
I talked to John and ECS and he said he has sold hundreds of these head gaskets and hasn't had one customer come back with a complaint.

Oil cooler ideas w/ links.
Oil cooler cap: http://www.rallyroad.net/content/oil-cooler-cap
Thermostat: http://www.summitracing.com/parts/ctr-22-480/overview/
Cooler(s): https://www.cantonracingproducts.com/cgi-bin/commerce.cgi?search=action&category=2350
- Not sure of what to do with the cooler size. I haven't measured anything yet but thinking I could run two of the smaller Canton coolers in tandem behind and to the left and right of the kidney.
Or do I just go S54 oil cooler and call it a day?

Ideas of where to mount another gauge? Don't want to do the A-pillar.
