96-98 Cobra head (spark plug) question

[SVT32VDOHC]

I'm gonna change plugs in this motor I have sitting around. It has 95K on it and it ran excellent before I pulled it out of the car. My main question is how many threads do these heads have for the plugs??

I know the 2V's blow them out (I had it happend to me before) but I haven't heard of this on the 4V heads at all.

Anybody have some info for me? How about torque specs?? Thanks.
