That's exactly what I was looking for.  That's the best information I've
found yet.  I have basically one of each of those heads in the garage.
Shockingly, although the 1.38" valve heads didn't come with the biggest
valves, the ports are by far better in that casting number.

Ok knowledge question


Spitfire heads, there are a lot of numbers.


Can someone tell the difference between the heads other than valve size.


ex: are big valve and small valve head ports the same other than valve size?


I know some have air injection ports, but those seem to be irrelevant. 


Just wondering if the ports are different, or if they are all the same
