what advantage does this give? I thought RS4 heads were reworked by cosworth?

i dont know how true..but some say the OEM RS4 Cosworth heads are prone to cracking. And they say the 2.8 A4 heads are sturdier and have big ports too...I just know how it compares to the OEM Cosworth heads in size.

they crack from valve to valve and valve to spark plug. needs to have been running very hot to do this, 2.4 and 2.8 heads have larger ports
