Torque Pounds?
 

Installing exhaust headers to 2003 boxster . I broke off 3 bolts getting old exhaust manifolds off , all retaped just get different # for torque pounds ?

I'm trying to decipher your statement or question.

You are working on your exhaust manifold, and broke three of the manifold fastening bolts.

I honestly couldn't follow the rest. You use a question mark in your thread title and last sentence, but it's not clear to me what you're asking.

Please restate the question or clarify your observation?

("Re-tapping" or re-threading might be what you did to the threaded aluminum hole in the cylinder head after you damaged the original threads extracting the broken bolt, I suppose?)

Use the same spec as listed in the manual for the original bolts. Use new nuts and whatever hardware was there before; washers etc...
