You cant use 2 Intake cams , like stated zx2 cams would be a step back
short throw shifter , under drive pulleys , light weight fly are not going to make him any straight away HP or TQ
406 gear would help IF he can get the gearing right which is very hard to do
Yes he can shave the head more IF he is allowed to run a higher octane fuel 100+
STG2 cam you can hear them lope and he would be busted when he started the engine in the pits , thats why I said STG1
SVT header would be legal because it is a stock Focus part that came in his car and body type , I have won this protest with 3 of my customers
I do about 15 racer both dirt and road , it would help a lot more if he would give more of what he can and cannot do rules
