what is the torque specs for cast iron heads on a 1989 camaro 350 tbi? thanks ty.

The same as every other SBC. Buy a service manual.

i have one and it dont have anything bout it thats why im asking on here

Come on Stephen, give him a break.

The final torque is 75 ft-lbf. However, I torque my heads down in four stages. I do 35, then 55, then two passes at 75 ft-lbf.

First clean out the threaded holes and put silicone sealant on the threads. Start with the middle bolts and work out to the ends.

Make sure you have good head gaskets for your purpose. I have been using Felpro 1010s (if I remember correctly).

thanks doc that helps me out a lot

I use 65. Doc, are you talking about some kind of aftermarket bolts?

My 1987 factory shop manual states that the torque specification for cylinder head bolts is 60 to 75 ft-lbf, pg 6A3-31. This implies that you are using GM head bolts. So, I am at the top end of the spec. However, I have been using ARP head bolts and they spec 75 ft-lbf. Another provision is that this is for cast iron blocks.

I am sure that 65 ft-lbf would be just fine. How accurate are our torque wrenches, anyway. I use Craftsmen tools and I resign myself to accepting their torque markings as Gods truth.

I was referring to stock bolts, iron block, iron heads, which I don't think I have ever seen 75 used for.
I use a Snap-on torque wrench, and I don't think the warranty expires on that after 90 days like the craftsman ones.

65ft-lbs is plenty. Thats what I've always used.

Look on Google images, and you can find a pic of the torque sequence for the heads (what order you torque the bolts in).
