What is standard on 185 Kw 302?

[kiwikid10]

Hi there,

I have a 99 AU1 Fairmont, It has K&N airfilter, Tickford snorkel, Jim Mock extractors and exhaust, this is supposed to get it to the XR8 195Kw range. :

What heads did these engines come with,GT-40P's? and I believe that they run the explorer intake manifiold, can someone confim what the heads and intake manifold are so I can plan my next mod attack, not much point sourcing things I don't need. :

Regards.
