as far as i know there is no difference, they are really nice in quality. the only reason i went with the coated ones is because i drive in the salt, the winters here are harsh.
And the only reason i got the cats is because i need to be legal in WI for emmissions just a visual inspection, and once every 3 years i have to get it on the dyno lookin thing they have and pass it there as well.
Ya no problem on the tools thing, i just picked up the adapter for the aircompressor to hold the valves up for a whole 8 bucks.
And i have a garage to use for 3 days so i think its going to turn out pretty good, just have to call allen and get a tune, and waiting for Thunder Racing to get the patriot golds in tomorrow and that package will also be on its way.
And the timing chain should be here by thursday i believe. Im gonna take tons of pictures.
Im gonna spend friday afternoon draining the coolant and getting everything ready, and do the exhaust and then saturday hammer away with the cam swap, and then sunday break it in and beat it up.
