I have recently moved back to CA from NY and have to replace my Pro Chamber with the stock H-Pipe. I want to replace the lost power with something that is "legal" so I was thinking of putting on some stage 2 ported heads (with a tune). I know I wont pass if I use aftermarket cams with the heads, but will the car pass with just the stage 2 heads? Seems to me a set of ported heads will more than make up for the loss of the Pro Chamber. I expect something around a 30-35 HP increase from the heads, to counter-act something like a 10-15 HP decrease from removing the Chamber.
Any help, thanks
