Why don't you give LG a call?
I'm sure you'll get the best advice from them.

Big heads and cam are at the breaking point of stock injectors. I'm sure the duty cycle is getting pretty high. Personally, I would go with the SVO 30lb'ers.(act like 36lb'ers on our fuel pressure)

This is the first I heard of needing an injector upgrade with the G5X-2. I am in the market for heads now. Will I have to start looking for 30#ers as well???

I used the stock injectors. I see no reason to add new ones.

If you get just the cam, don't upgrade the injectors. With Stage 2 heads, I would highly suggest it.
