Any other tips? The shop said they “Couldn’t get it to seal. Still pissing bad”
Make sure everything is clean and as smooth as possible, and use a generous coating of waterproof grease.
I've noticed a lot of the coolant tubes with fairly heavy corrosion and pitting that might cause sealing problems. Make sure there's no white clots of corrosion stuck in the head. If the tubes are pitted bad, the pits will have to be filled or the tubes replaced.
I think you can even double up on o-rings if needed.
