does anyone know where to find head studs for these engines. notorious for head gasket problems and wanna fix it right , the block is good. its a 16 and still has a closed deck block,

i found out the 2.3l seems to be running the same type of head bolt. arp offers head studs for that engine so im gonna try em
The 2.3 is basically a stroker 2.0 with an open deck.
2.3 head studs should work.
right on!!! i ordered Arp 2.3l studs yesterday, i did a head gasket on this car 20,000 miles ago its stock the only thing i could figure out that was bad was the head gasket, the block was straight head was also straight but i got it decked and tested just in cause something was going on, now it has a bad head gasket again and i wanna not have to do it again, its my friends car and gonna see if it holds up better with arp studs instead of those thin bolts factory uses, i do alot of 3.5l EcoBoost rebuilds and haven't had any high milage / abused ones come to me with head gasket issues, that doesn't seem to be their weekness . they have way bigger head bolts stock and are clamped way tighter, i still throw arp studs in them to be more tune friendly, my theory on these closed deck 2.0l ecoboost is the head doesnt have enough clamping force to block and its taking out the head gaskets / the 17+ 2.0l ecoboost head gasket failure is a whole different story tho im open to opinions and advice??
im a 3.5l ecoboost fan !!!! i have one with 320,000 miles trans is original engine was rebuilt at 280,000 miles my uncle has one with 350,000 miles, everything is original except for the turbos and exhaust manifolds, possibly someone did timing job years ago before he bought it, my cousin has one that has over 250,000 miles, truck is original me and him rebuilt the turbos and changed the timing at 200,000 miles, but then not everyone has that kinda luck have a truck come to the shop with 120,000 miles snapped chain and bent valves, he replaced the chain and guides 20,000 miles ago, had another one come in with a stretched chain at 130,000 miles owner wasnt worried about oil change intervals just drove the truck till something acts up then bring it to the shop, my experince/ theory is that when guys dont change their oil on time and let sludge build up there is no end to timing issues but its hard to get it into people that the oil life monitor from factory is a joke, on my truck it lets me go till 10,000 miles on oil changes if i would let it, it has no clue what kinda oil i am running just my 2 cents
Where's the gasket failing at?
I mean, more+even clamping force is always a good thing, can't go wrong there... But usually head gaskets don't just fail for no reason, even a very very pit in the head surface can lead to a leak and eventual failure (ask me how I know lol)
Flat sealing surfaces are only a part of the equation, surface finish is also important.
The issue is the saw cut block. Thermal cycling wears away at the gasket. Head studs arent likely to fix that. Ford knows about it, and is exactly why the block design was changed for later models. Believe it or not, I actually have insider knowledge about this, and has been a known issue. Newer blocks are drilled not saw cut, and have rff rather than buckets.

My understanding is that the 2016 and earlier blocks are similar to the desired 2.0 ST blocks and that in 2017, Ford started using a 2.0 block similar to the pre-2020 2.3 block, which eliminated the passage behind the turbocharger and with the steam slits between the cylinder block's combustion chambers.
Curious, what modifications and tune does your friend run on his 2.0 motor?
Off Road/Quarter Mile Drag Car/Not Street Legal
2018 base Ecoboost Mustang, 10R80 automatic transmission and 01A optional factory electronics
Modifications: Custom dual feed 3x3x4 air intake, NX 11910 Turbocharger, Aftermarket and custom charge pipes, Turbosmart plumb back BOV, Air to Air intercooler, Auxiliary water to air Intercooler, Port Injection kit with auxiliary controller, 3" turbo to rear axle drag pipe, trunk mounted battery and icebox, Drag radials.
we are gonna try this and see how long it lasts. i machined the head last time and it was glass smooth carefully cleaned the block. its the closed deck block as far as the block issues i thought ford had issues in 17-19 and fixed that block issue in may of 19 i wasnt aware that the 16 had block issues , to me it seems somthing is taking the head gasket out. i think the car is stock tuning but i wanna read it and compare to a stock file to make sure, the reason i thought its a streched bolt issue is cause of how flimsy these head bolts are on these engines they backout with a 3/8in, ratchet, the 3.5l head bolts take all you can do with a 1/2in, breaker bar, the block is straight / clean and the head isnt warped,
I'm not aware of a 2016 and earlier 2.0 block issue (I have a 2014 block and motor with single scroll turbocharger, in my Ford Fusion), under normal operation. However, I've been told that they are factory assembled with single use head bolts, which are prone to stretching under higher than normal boost.
The 2017 2.0 block, equipped with the twin scroll turbocharger, had similar issues as the pre 2020 2.3 motor. Ford eliminated the block canal behind the turbocharger and added steam slips between the cylinder walls of the combustion chambers.
Question... Did Ford switch from the stream slits to stream ports after May 2019 and/or 2nd generation connecting rods, as they did with the post February, 2020 2.3 motor?

Im not sure on the exact date when they switched block design. I was building them as prototype development engines in 2015. I want to say it was 2018/2019 when the blocks switched to drilled steam ports vs the saw cut blocks. Dont quote me on the year though. Its been a while since I worked on those.
