Overheating again... Blah

Okay so background: I have had on and off problems with keeping water temps down since I got this car. Seems like its always something. Anyway radiator has been replaced, thermostat and water pump, coolant flushed Multiple times. New eBay slim fan.
Last summer it would have temps start to go up on grades but all I had to do was slow down and keep it in check. This summer I've had an egt gauge and have never had a problem till after I installed my turbocharger and intercooler. Now I'm running the intercooler in front of my radiator which I was worried about at first. But now I'm not so sure that is it. During the first few weeks I didn't have any problems. Then I started to see temps climb if I was hot rodding for a bit. Then it would start to get hotter if I wasn't on the highway.
Now at idle it will raise the temps up to about 3/4 or so, the fan kicks on and off but the coolant steaming and bubbling. So it's gotta be overheating. What's wierder is on the highway The temps stay way down around the 1/4 mark but if you stop it seems like the car has been puking up some coolant.
Anyway at this point I can only guess headgasket. But I'm confused by all the wierdness and don't want to just try out a head gasket...

Yeah the car is parked. I need to go ahead and pull the head I guess... Assess and make some decisions

u can do more tests like leak down and stuff, but its never bad to pull the head, its not that bad of a job and then u can see the condition of everything and install head studs ;^P then you really know what you got.

Yeah I guess you are right. I just did the water pump a few days ago and had the timing belt off. I should have done it then :-p you live and you learn.
What actually causes the overheating? Is it exhaust gasses into the Coolant?
Wheres the best place to order headstuds? I'm finding them for around 180-200$ I thought they were closer to 130$ somewhere... But that might have been for the escort studs...

Summit racing was the best for me, but there are others cheaper with shipping for others I am sure. Been a while since I had to buy studs. 180 sound about right for the vw ones

Weird. I kinda thought i was losing my mind..
Oh well. I'm just happy to have tapatalk back!
Anyway so I ordered a 2 notch gasket since mine was technically in 2 notch range from all the measurement I took.. But I'm still scared since a 3 notch was on it and I haven't ever measured this before.
If its going to be a problem it will show up during timing when I crank the engine over a few rotations right? Its valve contact we are worried about right? Or is it more an issue of efficiency?

yes you will detect any valve contact issues during turn over, ull be ok dont sweat it.

I had a similar overheating issue... new HG with hylomar seems to have solved it.
(I don't think the gasket was leaking between cylinders, I think it was along the back, hence the red rust on the coolant passages near there.)

Hey the head shop loosened all the cam retainer things (arches? What's the technical term for these) is there a specific torque pattern for these? Also what's the torque? (My computer crashed that had my Bentley on it.. )
Im putting arps on it. I defy it to blow again... Is there any 1000 mile retorque with arps? These with a fiber gasket should be good for 20psi right?

Yes, there is both a specific torque value and a specific torque procedure. My Bentley is nowhere near me at the moment though. If you don't do it right you can bend the cam.
ARP studs are fine for 20 PSI. Really stock stretch bolts are OK at 20 as long as you aren't running high EGTs or exhaust manifold pressure. No retorque is required with ARP studs.
