tourquing HD head studs?

[bigbad400]

what torque do you set the gtthunder studs to. i broke one at the stock 33ftlbs had to replace them and hopefully tomarrow they come in, but i dont want to mess them up... so those of you with 440s what do you torque your hd studs to?

[RIDEREDson]

Torque them to 450 ft/lbs

j/k had to do it...

You broke a GT HD stud at 33ftlb? That just makes me like them even less. What did GT have to say about this?

I'm not running a 440 but I do have an 11:1 piston and I torqued mine to 34. I have had not problems and I beat the crap outa mine.

gt thunder never heard about it cuz i got the cylender with the studs installed... i put a 440 sleeve in it and went to run it, ill set them at 34ft-lbs to start but what if i have a head gasket leak then what do i do? they dont have a "recommended torque" or anything?

Just remember that you are tightening down onto and into aluminum. Overtightening may cause the aluminum to fail when it gets hot. For this reason I only went 1 foot lbs. over factory specs.

Just a suggestion......Maybe try calling Gt Thunder??

[bigbad400]

why do you not like gt thunder. the studs are only rated for stock torques but the threads are whats bigger, it has deep long threads the stock has short skinny threads. they are the best thing you can get for the 440 kits and like. and decently priced.
