Can someone tell me what the torque values are for the rocker studs in the alum. heads?
Thanks

 

50 ft/lbs total. 25 starting, then finish it with 50.

 

Could you guys let me know along with putting Thread sealer on the bottom of the studs ARP should I use blue 242 or red not sure of the number just on the top of the threads to lock them in Seems from the factory there was red of some sort at the top of the old studs ...unless that was to install the steel inserts for the studs in the heads?

Thanks Chris

 

ABSOLUTLY NO locktight on rocker studs! W/ alum. heads you'll damaged the heads. No need for thread sealer either.

 

Thanks about the locitie but there is Steel inserts I guess GM used RED when they install them, Not sure why You say it would damage the heads since they are going into steel threads....

Anyways Llyod told me to use Thread sealer as when he ports the heads a few of the stud holes get opened up into the intake ports.. So I guess thats why he says to use Thread sealer...??

Thanks

any thing else you can add?

Didn't know you had ported heads, yes you'll need thread sealer then, the kind to use when sealing waterjacket threads on some of the head bolts.

GM used heil-a-coils on the heads for the rocker studs threads, if you use locitie it will ripe the heil-a-coil out and you'll have the same issue another member has hand on this board lately... its not fun. No other tips, you should be set.

 

Thanks alot,

Sorry My mistake I never told ya I had Llyod HEads on that...

Thanks again...

Chris

 

I would coat the threads with teflon thread sealer as the studs could protrude into the intake runners.

 

Your correct, i was thinking he had a set of stock lt1 heads. You need some major ported heads to have the rocker studs holes in the intake runners. Even if you can't SEE the holes doesn't mean you dont have them... when your pushing as much air through an engine as it takes to produce as much power as we are getting these days, even the smallest hole can cause undesired effects.

 

Yup all is done coated all the studs, Now on to the heads same thing coat them bolts as well, Plus water pump bolts I guess...

 

I wanna say last set i installed said 55ft lbs with ARP lube or sealant, and yes you need that on the intake studs if the heads have been ported.
