How many valves

[mr. shr]

Hi all,
Just a quick question. I've been running around the office here boasting about my recently purchased S class. It's the 4.3 litre V8.

I've been saying that cos mines a V8, it's got 32 valves.
But looking at the tech spec on Parkers website, it says the V8's have 24 valves.
How's this happen?

I thought nowadays, all cylinders were two in two out?!?

' ...... Through the use of three valves per cylinder, twin-spark ignition, air gap insulated exhaust manifold and high-capacity catalytic converters, the ML430 has the technical potential to meet the strict US emission limits for "Ultra Low Emission Vehicles" (ULEVs) and Phases 3 and 4 of the EU exhaust standards planned for the years 2000 and 2005 ..... '

It's about an ML but the engine is the same .....

I think that I can say that the engines have now gone back to 4 valves per bore and single spark plugs from 06.
