Im about to pull the head off my D16Y8 and replacing the headstuds. my question is, after u hand tighten the studs into the block what do u torque them down to?

 

you are removing and replacing a head without a shop manual?!?!?!

http://www.helminc.com

DO NOT DO ANYTHING TILL YOU GET A SREVICE MANUAL
there are specific procedures for doing that, if you do not do it in a correct order you can EASILY warp the head, aluminum warps easy.

 

i have a helms in my comp but i think that part of manual is missing, cuz it doesnt say anything about torquing them into the block. ive been doing my research for the past couple weeks,and this is the only question i have, thank you.

 

ARP (if those are the studs you will be using) says in bold to put them in 'HAND TIGHT ONLY'

 

Double nut them and torque them down to b/w 5 and 7lb*ft.

The instructions and ARP's recommendations explicity state that you shouldn't tighten them anymore than hand tight, but many people torque them down to keep them from backing out when torquing the head down and keep the proper tension on the stud.

It also helps when removing the head, when they're torqued down, so that the studs don't loosen or back out when loosening the nuts.

I believe the reason why ARP says not to go any more than hand tight is b/c you can strip the threads in the head if you keep tightening them.

i saw that, but im double checking to see if this is correct. i wouldnt feel safe if i just hand tightened the studs.

 

if you think about it, the studs are just a guide for the nuts that actually hold the head in place. so providing the studs dont back out when installing, once the nut is torqued down it is secure.

thanks, great info...
definitely answered my question

 

side note: the new(er) ARP and AEBS headstuds have an fitting built into the top of the studs so you can tighten them into the block with an allen wrench
