Intake bolts question/opinions wanted

[70SwingerGuy]

340 with Edelbrock heads/intake here, and I want to change intake manifold bolts. Will it be ok to change/retorque them one at a time without having to pull the intake off, new gaskets etc?
I personally think it would be ok, but I tend to overthink things and just wanted to check with the experts here
Thanks FABO

 

[mygasser]

yep, as you say 1 at a time and you'll be fine.
neil.

Thanks Neil, much appreciated

 

[4spdragtop]

Yep, one for one!

 

[MoparLeo]

Intake yes, cylinder heads, NO.

 

[RustyRatRod]

No problem at all. It'll be fine.

 

[junkyardhero]

be sure to throw some sealant on the new ones. other than that, go nuts.

 

[RustyRatRod]

What kind of intake bolts are you using? I like using stainless, because the chance for rust stains later is non existant.

 

[JDMopar]

One at a time is fine, plus I'll be the AMEN corner for putting sealer on the threads of the new bolts. It will prevent oil from wicking up the threads and ponding up in the intake.

I hadnt decided for sure yet, either some 12 point black ARPs, or some black socket cap screws, I like stainless a lot too, but I have kind of a black theme going on with my motor

I had planned on using some anti-seize due to the aluminum heads, or I heard that ARP supplies a lube that has to be used if I go that route

I agree with hootenanny up there about using sealant on the bolts. I'd use black RTV. It acts as a sealant and anti seize. Anti seize won't seal. RTV does both.

permatex 59235 is what you want

or like spanky said some good ol' RTV will do the job too.

i would strongly advise against allen socket caps. they can present a problem with tool clearance on the inner most bolts where the room is limited due to the plenum of the manifold.

basically, the allen socket is too tall to get in there.

*manifold dependent, naturally

Yeah and I was gonna recommend 86in the 12 pointers. I've had too many of them strip. I like the reduced hex head intake bolts kinda like header bolts.

i'm ambivalent on 12's

if they're good quality, sure why not. but hong-kong phooey ones that strip easy and stainless that rust? miss me with those, thanks.

the reduced head ones are nice, but kind of a chore to hunt down. i think mcmaster has them though.

Dang, I only have 80634

That also is good info, Ill have to check that out before buying anything
EDIT: Just had a DOH moment here, socket cap is what I have on right now ...haha
Thanks guys

If I go the 12 route, it will be with ARP, so no worries there

oh! i didn't know they sold that as a stand alone kit now!

good to know...

So heres a question, if I go the ARP route, would I just use the lube that they supply and never mind the sealant? Ive read that you MUST use ARP's lube if I comes with their bolts.
Also, according to their spec sheet, they recommend a torque of 45 ft/lbs for a 3/8 bolt, but isnt the torque according to Mopar supposed to be 35 for the intake bolts?

 

[CFD244]

Just spit ballin'

If going with ARP, do they not typically have a substantially higher torque spec? Thinking that I would torque them to OEM values one at a time, then once they are all changed......Torque to ARP specs in the recommended pattern.

LOL.....Treed by the OP

Yup, 10 ft/lbs more in this case

I would ignore their lubricant, clean the bolts thoroughly and use sealant. In this instance, the bolts are threading through the heads and into the crankcase. You will have oil migrate up the threads and pool on the intake if you do not use sealant.
