What does everyone torque their alum. intake manifold bolts to?

I assume your talking smallblock? I torque them to the factory specs 23-25 ft/lbs.

Sorry, Its alum.headed 521.
Original spec is 30ft/lbs for iron manifold/head but I thought it might be a little higher with the alum. parts.

I would go with frdnut said. That's the specs I used for my aluminum intake.

Thanks guys. When I get the C-6 back in an running, I,ll do them to 25 lb.

I have a 289 with GT-40 steel heads with a Stealth intake.
The mounting bolts (ARP Moly) will not stay tight. At least once a week I check the bolts and at least (4) are always loose. The same thing happened with an AirGap. Go figure!

As a bit of humor...
1

on't walk away from your engine...not while a buddy is helping, after one too many beers
2:upon getting the 5th beer for your bddy, and you are on your 7th,
try to remember to check your setting on the torque wrench to insure your buddy set it for 25 foot pounds, and not 65 foot pounds like he thought it needed to be on an 351c 2v.
3:come running, when you hear the very last bolt snap flush with the head
4:make your buddy pay half, for the machine shop to fix the problem, and then spend $540 for a complete reconditioning.

Oh dear. 65lbs!
