gmmg is kinda like berger for camaros. different performance packages from light mod, 25-50 hp increase, middle about a 100hp increase, and 150 increase for all out. those heads probably came off of the all out package, and those packages are usually pretty rare, because when ppl ordered these special edition cars with different performance packages, usually they have no clue about the car and how it drives and would be too scared to buy the top end package. in most cases those top end packages include:
high flow CAI
headers able to meet CARB standards
high flow 2.5 - 3" cat back exhuast
high flow y with high flow cats
after market intake of some kind, more then likely from bbk with matched TB
high flowing heads with larger valves, springs, rockers possibly
larger injectors
high flow rails
tune
maybe a couple other things here and there with suspension and driveline
get the stamp number, and if the car they are coming off of is the original car from gmmg, get the year and vin also or build number and contact gmmg themselves
