so this is out of a passat i've been told, is a 2litre 16 valve, but has milder cams than a kr, right? is it a tall block or was that the abf lumps? if not a tall block whats the deal with these? any good? also been told that its a good idea to use the kr cams to get a bit more ooomph out of it?
any info, advice etc welcome!
