Default RS4 heads VS. 2.8 heads

alright, i've done a lot of forum searching and haven't found any good information i can use to make a decision. I'm in the process of building a Eurospec 3.0T block and the next step is heads. I've found that the 2.8 heads seem to match up to the RS4 intake pretty good, but i want to know exactly how well. Also what advantages/disadvantages do the 2.8 heads have over the RS4 heads?

The main reason I am asking this is RS4 heads are nearly impossible to come across while the 2.8 heads are almost like walking down to the corner store.

While on subject, any additional info i can get from you guys about other head/motor info you can help me with would be fantasic.

Default inside>>> afaik

the 2.8 heads are almsot exactly the rs4 heads, although the rs4 already have the sodium filled exhaust valves and rs4 cams, the 2.8s would need to be port matched to whatever intake manifold you would use. the rs4's are basically fully modded 2.8s ready to go. 2,8s need port matching
rs4 or other cams
sodium filled exhaust valves, etc. go with 2.8s and have them worked to the max, and itll still be cheaper than rs4's
