Could someone tell me how much power I would get from this?

My current mods are as follows:

2-1/2" SLP y-pipe
SLP 345hp LID w D/D
FTRA
Whisper MAF ends
Mufflex off-road pipes
Super Yank 3500

Dyno before converter @ 2500 miles ~ 330rwhp/350rwtq (corrected)

Are headers a must with the stock cam?

Thanks

No but it is a good idea to put in headers before doing internal work.
