guys i need some help i have a b18 drag car 6-800hp what head studs shall i use and how much lbs should i torque it?? head has lifted twice so far some one plz help me

 

arp or golden eagle from reading on here seems to be most people torque to 80-84 ftlbs

power doesnt have anything to do with it though the amount of boost pressure does

 

ARP 70 ft lbs

 

may people argue for both head studs as well as what you should torque them to lol

 

I tork my head to 100ft

 

100ft lbs is a lot! which studs are these? and on which head gasket?
probably warp the head doing that.

 

originally, a few years back, arp stated 65 ft. lbs. not it's 85 ft. lbs.

10-20 ft. lbs is a big difference.

80-90 ft. lbs is not a big difference.

 

Ge torqued to 80 with oring.

 

what headgasket would use all recommend?? what do use think of l19 cosworth headstuds? cosworth headgasket?

 

here your going to get answers such as

oem
cosmetic
golden eagle

thats it

 

OEM headgasket, ARPs torqued to 85ft/lbs.

Why has your head lifted 2 times? What does yout tuner recommend?

ARP Here 2 steps 60 then 80 with Ultra Torque Lube (Important)

 

what do you mean 2 steps 60 then 80?

 

Really?

Torque them ALL to 60 in your cross cross pattern (per the service manual)
when your done doing that, then torque them to 80 on the second torque step.

 

Why do you think your head is "lifting?" I read your other thread about your head lifting with arp studs and GE gasket. Clearly you have some other issue that expensive cosworth parts aren't going to fix. I would look at other things like correct torque on the correct studs, clean and flat head and deck, clean headgasket installed CORRECTLY, and use molylube. Is the tune junk? Did the headgasket blow twice from knock? Just my .02

 

are you sure your tune is ok?

 

That's awesome!!! Gotta love those 12mm head studs

 

what studs are those 12mm?

 

the first time the car over heated cos the fan was on the wrng side the i used golden eagle headgsket and my old arp studs im sure my tuner torqed them to around 80lbs nw the car is leaking oil from 3 corners of the head but hasnt over heated yet.. i dnt knw what to do my tuner is **** you guys have the best tuners... need help

 

arp h22 headstuds, i think that is what theyre talking about.

 

ok so i make less than 600hp but will be in the 500 range after i tune. i used the arps and a golden eagle 84mm vtec gasket.

i do it in 3 steps, 25/50/80ftlbs with the arp moly lube.


check that timing if you keep lifting heads, either in the map or at the distributor

 

you probably just answered part of the problem for us, you overheated the engine and probably warped something in the process... take the head to a machine shop that has a straightedge and check it... might not hurt to check the deck too.

how many times have you torqued your studs?

 

i had the head skimmed but not the block my tuner didnt mention that to me..
it has high comp pistons what head gasket would i need to use if i have to get the head and block skimmed again bcos i dnt knw how many times it has been skimmed before aswel

 

what are the symptoms? burning coolant? mixing oil?

The head and/or block is probably warped. Or overheating it cracked something. I would just buy new studs and headgasket and have the block and head check for cracks and flatness. Cut the head and block if needed.
