Just curious what the manifold will be going on?  The dragster?  I have worked, modified, tweaked, built, ported, even made acrylic spacers, and I am trying to figure out exactly what your intensions are at this point.  Not criticizing, just trying to imagine your intended final product.  If you are making a single 4V, or something else, why not use one of Mummert's gaskets to get your dimensions for your manifold bases?  They are unidirectional, and a bit larger than the Fel Pro or Best gaskets.  Watching with interest.  Joe-JDC

Going home, got the flanges about 90% donee

Working today

Starting to make a Lexan intake manifold, this is the start of the flanges, using a old 6x2 manifold as pattern.

Shift cable installed, runs through the gears with no problems, still need to find the correct pin for the end of the cable and a bushing,
looks like I need to spend time and clean up the car (dirt from sitting)

Ok, that took an hour laying on my back on the ground and digging into the transmission.
  

Radiator, cleaned and installed stainless hardware, new problem
     


shift leaver points up I need it to point down, so now to pull the pan and see what to do.

I have a legal flex plate shield that fits, parts are hard to get now (long wait)

More work, refinished the wing and all small parts, finished with Sharkhide, all hardware replaced with aircraft stainless socket head bolts (fine thread) 

What am I doing? refinishing parts
