S4 / RS4 (B5 Platform) Discussion Discussion forum for the B5 Audi S4 & RS4 produced from 1998-2002

Are the heads on a 2.8 V6 the same as the heads on our engines? Assuming they are 5 valves.

Default Not possitive, but I would think they are not since the displacement is different. Same design, but

probably a little smaller.

I believe the heads on the A4, S4, and RS4 are all different.

Default Yup... confirmed.. ETKA lists the APB and AHA/ATQ engines having different heads..

part #s are different. Interestingly enough.. they list the MT and AT heads as different part #s.

Default Wait.. I take that back.. the part #s are mostly the same.. just the last 2 letters are different..

does that mean a different part number? Eg. 078-103-068-AP vs 078-103-068-BE.

Yes. Different revisions of the same part.

Default So does this mean its the same part or not!?! Remember.. we are talking about heads here..

it is the same part # but a different revision, does it mean they are all interchangeable?
