Alky Pro is being used by a lot of the top racers over here in Australia now very user friendly and Greg Gower will give you the after sales service if you need it .
There is a free two week trial version available on the Alky Pro site try that and you will buy it .
55° to 45° valve angle slightly smaller inlet port in the 2's but bigger exaust port .
Usually put the exaust port of the 2 head in the 1 for the update
I haven't run leanouts on my car yet but just got a 4 block Leahy EM setup and need the EM box to run it , Im running a Powergrid and happy with that for the timing side of it .
Is this what I need ir is there different EM boxes
I run the F.A.S.T air system in my car have never had it Fog up and I turn it on when I get in the car and its a lot more comfortable as it gets hot down here in Australia
