http://www.hitman.hm/ported.htm

and

http://www.hitman.hm/injectors.htm



should prove useful if you havent looked at them already.



some useful info from the first url:

Fuel : Air / Fuel Ratios



Idle 12.7:1

Cruise 13.8:1

Max Load 12.9:1



thats for a street ported 12a, hitman says similar for ported 13b.
