tl dr: No. There are too many variables. There are two things at play when tightening a fastener for an oil pan: How much torque can the fastener actually handle? How much squish can the gasket handle before it doesn't seal. Torque values for bolts will differ, due to size and hardness. An ARP bolt of any size will handle way more tensile load than its ...
The answer is no. Absolutely not. Those charts are not for automotive kinds of torque. Every "chart" or "table" about specific grades of fasteners are for achieving a condition called critical torque. This is very rarely the criterion for torquing automotive fasteners. Exceptions are head bolts, and certain suspension components. The specific torque ...
If you google it, there are charts and calculations out on t'interweb for torque, but for anything attached to a gasket, I'd make the extra effort to look it up (he says, after shearing a valve cover bolt on a Subaru engine last summer...)
There are standard torque charts out there. They are practical for steel to steel applications with static loads. In these charts the torque is defined so that the strain on the bolt is in the elastic deformation range. If there are gaskets, mixed materials with high differences in thermal expansion, high heat differences or dynamic loads involved you need a ...
You could look up the head markings in something like this and then use a chart such as this to determine a ballpark torque figure. It may not be perfect, but it ought to do in a pinch.Edit: I thought it would be a good idea to separate out the SAE marking and include in this answer. The jpegs aren't perfect, but they'll do.
