when i had stock bolts in my 12v i always went 130ft/lb, the headstuds im using now i torque them at 165 ft/lbs

 

wow thats alot.

 

can i suggest something??
My buddy who has a 96 is running this setup for the past 3 years now and has about 550hp to the wheels using stock head bolts.
You must do this in sequence. Take each bolt and torque to 90lbs. then go additional 5lbs on every bolt. wait and hour, go another additional 5lbs. wait an hour, go another 5lbs, wait an hour. keep doing this till you reach your goal. he got his up to 150lbs, it takes all day but its worth it. Now the reason why he waits a hour is bc he wanted the bolts to safely strech and set.
Like i said, this is purely his race truck. runs low 12's in the quarter on twin turbos. never had a problem. if you would like to contact him for more info i can give you his email address. very very nice/helping man. i go to him whenever i need help. he is a very smart when it comes to these motors. PM if interested

wow sounds like its worth it to me.

 

 

Sorry to bump this old thread up.. But I decided to use the above method since I cant turn a wrench 90 degrees in the E350 and the short block had to go in first.

I'm at 115 ' lbs now and I have two questions..

While torquing down, Ive been going back for a second round without changing the wrench setting.. Is that bad practice to recheck? Should I just hit each bolt once and move on instead of checking? It makes sense because you should get a bit more with help from the other bolts. But end result I'm not sure of.

And second. Should I continue higher up to 125 ' lbs? This is a 1990 converted to IC otherwise stock. But getting back to the bolts might be a big project after its together and running.

Thanks

Btw.. When I think about the factory torque specs and then another 90 degrees. Doesn't that seems brutal on the bolts instead of 5 lb increments?
