I am using Dynomax headers on my 454 in my K20 and they fit with a bit of massaging of the frame on the passenger side, drivers side fit perfectly. The ones I used are Dynomax 67-87 2WD BBC headers, part number 86022.

Here is a link to a bunch of pics of them installed.

I would note I will be using a hydraulic clutch and it does look like the factory clutch linkage would be a problem.
