From memory TODA sell their cams in 2 different lifts, standard and big. The standard lift cams (but big duration) can be used with stock valve springs and everything. With the big lift ones you also have to buy their upgraded valve springs. Along with adjustable cam gears to suit, I hope that's all the parts you have to buy.
The 20v has the shims under the bucket which is good.
You also need a degree wheel and a dial gauge and know how to set it up. Otherwise it should be good to go. ... then computer tuning.
