would the difference in performance be significant in changing from a stock ATW head and cams to an AEB head with aftermarket cams?

the setup is just a K04 with adjustable fpr, red top injectors (310cc), fmic.

also thinking about getting fuel rail from atp and porting and polishing or extrude honing the intake manifold. trying to see the most i can squeeze out of a K04 for now

It's hard to say, the cams aren't the restriction in your setup, it's the turbo.

You'd also have to change the manifold, since the AEB ports are a lot larger.

Considerring the cost of cams, AEB head/manifold, misc gaskets, porting/polishing, and labor, you might be better off just saving for a bigger turbo, much better HP/$ ratio.

Also, forget about the ATP fuel rail, if you're not maxing out the fuel system, an upgraded fuel rail will do nothing but lighten your wallet.

was just curious about this cause someone offered me an AEB head for a relatively good price.

im probably going to go with a larger turbo after not too much longer but was just curious if there was any more things i could do with this turbo.

again thanks for the helpful information
