what is the torq down on the header bolts on a 302 engine?

Iron or alloy ?

This is some stock info I had in the file, but be careful as aftermarket parts can be significantly different. Good luck.

Mine was 70 on my 73 and it said to torque in 3 stages following the diagram above first 40 then 55 and finally 70

That looks like head bolt torque. Aren't you looking for exhaust bolt torque? I wouldn't go more than 20 ft lbs on the exhaust, if you can get a torque wrench on them.

I think someone is confused here.

HEADER ( exhaust manifold ) or HEAD ( Engine head ) bolt torque?

header, exhaust bolt torq. they are headman headers if that makes a difference.

header, exhaust bolt torq. they are headman headers if that makes a difference.

Are you using paper gaskets? If you are, DON'T! They will leak and you will get pissed off. Even if you soak them in water first. I recommend using the graphite coated or copper gaskets. Proper torque I believe is 22 ft lbs. Don't quote me on that but you should run the engine to operating temp, retorque them and run for another week and tighten again. After that, you shouldn't have any leakage issues.

No Problem...........Only time I have ever had one leak is when I used paper gskets. If you use either of the other fore mentioned ones, you won't have a problem. - Mike
