I honestly don't recall if there would be a way to make the Zetec dipstick work, but the SVT one is relatively cheap. I'd just pick it up to be safe.
Also, I've done this twice now, and can confirm that the 50 ft roll of DEI is just enough to get the header wrapped. When I did it, I wrapped on tube (without cutting off the roll at all), measured the length I needed, and then cut four lengths of it (the tubes are equal length). That way you don't end up using too much on one tube, and not have enough to finish.
Oh, and the non-titanium wrap (the white or black stuff, not the 'carbon fiber' looking stuff) does not need to be soaked in water to be put on, but I could see how that would help. It does, however, need to get coated in their silicone spray to seal it, otherwise it will let water in. The titanium wrap doesn't need to get sealed.
Zetec....is that like Vtec or something???
