 Super cool article. It looks like they wrote it before they ran the engine. It would be cool to see the dyno sheet. 
  Seems like they were still working on getting it running when the pictures were taken.  They still needed to put pipe plugs in the manifold and hook up the exhaust.
 When was this written, I've never seen this before. A guy on Youtube said he knew the guy who built this engine.
 Thanks for sharing it.

 Watch out for the oil hole.

It looks pretty normal for no short turn work.  I think a 210@ .500 lift could be had with decent short turn work.  Some cross sections would have to get opened up if you wanted bigger numbers.  The short turn has some metal in it , 289 heads are pretty thick.
 You want to limit overhang on the short turn.

How much does the shaping of the short turn increase flow?
Quite a bit.  These heads are very small over the short turn so the speeds are very high.  If the short turn is wrong this head will plateau off at .450" and the swirl will go through the roof.  So look at the flow sheet at .450 and draw a straight line to .600 and that is what the flow will be. The swirl will jump about a 1000RPM so low 3000's.  When the short side is poor the flow zone shuts down and creates a nozzle.
  Short turns help with valve lift.  If you always run cams with .450" lift your shorturn skills don't need to be spectacular. You may even see some small mid range power losses with a swoopy short side and a low lift cam.
Its all about .25 L/D ratio.  Below that the curtain area is is controlling flow, so the port velocities are lower. Things stay happier.
Once you get over .25 L/D the flaws show up fast

Interesting.  My 64 1/2 mustang was built in late April 64.  Had the C5ae 289 1.78 heads but was a generator head.  3/8" bolt where alternator should be.  64 1/2 mustangs were generator cars.  But something to think about when using an older head.
