Question on headers

[cragmor]

I have not found anything by searching. I have a 76 C10 step side that has been lowered. I want to keep it that way, but I am concerned about putting headers on it. The stance is of a typical car, not talking low rider or the like. Will headers for this truck end up being too low with a 3" exhaust? If so, can I get headers for another modem Chevy with a small block that will work that might bring it up a little higher?
I have been trying to google this information, but not finding anything conclusive. Thought I should ask here where you guys live this stuff.
