I've seen a few 1000rwhp barras and SOHC 4l with 12mm studs and no issues I think most of it will come down to people not retorqueing studs after a few heat cycles.Sent from my iPhone using Tapatalk Link to comment https://www.fordxr6turbo.com/forum/topic/89944-head-studsheads-lifting/page/2/#findComment-1539983 Share on other sites More sharing options...

But it wouldn't harm cracking them off a little and retorquing. My experience just going around without cracking them off a little is that with a solid gasket like copper or steel the nuts didn't torque up anymore unless you had a soft head and the washers sunk into the ally.

turbotrana Member 2,586 Member For: 22y 2m 6d Gender: Male Posted 17/04/15 01:14 AM Share Posted 17/04/15 01:14 AM (edited) Just my personal experience. I took apart an e series engine that had been together just a few weeks (I was the fixer, not the phuckeruper in the first build). The deck had been machined and no coolant (only water) had been used in engine in the 3 weeks the engine was together.It used an AU MLS gasket. You could clearly see via slight rust markings on the deck that the water does seep quite far into the gasket areas around the water passages. The E series and B series engines like to push water on the exhaust side.When you think about it, it is pretty fancifull to think a layer of steel that has no give is going to seal between a machined piece of cast iron and alluminium.The factory finishes do a pretty good job, but if you have a bad machinist not so good.So although it will seal around the combustion chambers because of the pressing of the steel around this area, it does not seal very well around the water jackets.That is why alot of these steel gaskets are Viton lined (the ford mls is not). The other alternantive that I have used on copper and mls is threebond. But with threebond you got to be carefull that you dont block the water/oil passages and get it into the combustion chamber so got to be carefull using it. But it does work well I have found.I have never used hylomar but think this is a good option cause you spray it and less issue with making blockages. I would even consider taking a 3 layer MLS gasket apart and spraying inbetween the gasket as well so hylomar between each layer and against the head and deck.
