Coolant in #4 cyl. after headgasket job? HELP

Just had my '05 F250 head gaskets done (second time on this truck). According to OASIS and previous owner they were originally done by the dealer under warranty at 30,000miles by a dealer in Fort Lauderdale Fla. using ARP studs/OEM gaskets. My mechanic says there was oil/fluid in stud holes under studs causing the studs to back out!!! Bought the truck used at last year at 90,000 and so far have had really bad luck with it. The truck now has 100,000miles on it, has Sinister EGR delete, new STC fitting, I had replaced all down pipes/dummy plugs and o-rings and HPOP in HP oil system system. Truck started steaming/drinking coolant about 2 months ago so I knew I was in trouble. Bit the bullet and had the head gaskets done again ($5K) The heads were hot tanked, magnafluxed 2x to check for cracks, and .005" milled off face as they were warped (they took some off other side or valves to compensate?) Put back together using new OEM gaskets and reused the ARP studs. Got the truck back after the big job and the first time I tried to restart it after it sat for a few hours it rolled over half a turn, stopped dead for a second then fired and blew tonnes of white smoke. Turns out #4 cylinder is taking in coolant somehow and would hydrolock for a second, then get by and turn over/start. Brought it right back to the shop and after a few days they did a compression test on all cylinders and they are all good, but they are at a loss as to why that #4 cylinder is getting coolant in there??? Anyone with a similar experience or idea as to what could be causing this? Any help greatly appreciated.

Maybe your head is cracked near the injector cup. Unfortunately, the mag test is only as good as the person performing the test. I do that for a living, I realize you said it was done twice, wonder why? Unusual for you to say it was done twice.

Sent from my phone that somebody didn't help me get.

I'm betting since you reused the original arps that were used when the truck only had 30k on it the original installer didn't use arp torque lube as I don't think it was out or common practice then. Meaning the original studs were torqued to 245 ft/lbs dry which if there was fluid in the block threads could have over torqued the studs and stretched them. I they are stretched they are bad and can cause gaskets to blow.

seems weird they didn't pressure test a head that has injector cups that could be the problem

^^ Didn't even catch that. If you didn't have them pressure tested this is most likely your problem.
