6th Generation, What engine head is this?

[firejackal]

I have a 1999 Honda Civic SI, I haven't had it for that long, my knowledge with Hondas and cars in general (have a Thunderbird as well) is low.
This car has the engine that came with the generation (B16A2), but the head (I guess that is what it's called, the top of the engine) is different, would anyone know off hand which one it is without me taking it off to find a serial number on it (had it off before but forgot to look for it)? I plan on buying that cap/lid that goes over the sparkplugs, thanks in advance.

What makes you say the head is different?

The head should have some stampings righ about the exhasust manifold. Those 4 tubes that run down to the underneath of the motor.
