No such engine. Source:

I'm assuming you mean 4.6 V8 and the standard SOHC version of this motor has 16 lifters (1 per valve) while the DOHC version has 32. I also heard they came out with 3 VPC versions which would make them have 24 lifters in total.

But if you are talking about the 4.2 V6 engine, there are only 12 lifters.
