Ok ill put in my 2 cents
I have a 4 mill passion motor, with a cut and rechambered stock head. Works great and is stealthy, work jim did looks really nice.
Now that head put me at about 185 or so psi, it would be nice to be able to have the ability to change the domes and the cool heads do look really nice.
I dont remember what jim charged me for the work on the head but i know it was almost damn near nothing since he was porting the cylinders also (passion 12 port).
However i will be looking hard at a noss head here in the future do to the bling factor and ability to change the octane requirements of the motor.
Both are great mods and yield similar gains, it all depends on how much ya wanna spend and what your looking for
Stealth vs bling
Do you want to change octane requirements?
Its obvious the noss head is the way to go if you got the cash, but the stock head that is cut AND RECHAMBERED is not a bad way to go either if your tight on cash.
