I though I would post this here as well as I guess most of you guys don't visit the AU section on the "other" forum, but I could still use your help.

Shorly we will be working my brothers car, we plan to take the head out and do the following mods:
-Big cam, most likely Dev5, any other big cams out there?
-Upgraded valve springs
-Vernier gear
-Deck the head to raise compression
-Maybe a slight port job if I can get it cheap (mate knows a guy, lol).

I need to know the brands (maybe part numbers) of the springs and vernier gears and where to get them at a good price.

Also I have read that the AU's need the spring collets changed too(according to the JimMock website), is that true?

Will the head gasket and head bolts from ford be ok or is there a better aftermarket brand?

Sorry for all the questions but I want to be 100% sure before I start this as we will be doing a lot of the work ouselves(except for the porting).
