420A Building up my 420A-T

[Inkdlyfe]

So for the most part my 420A is fully built I'm looking to get more bolt ons for it now, the bottom end is built and now after bending all my valves I'm getting a built head, I was told to get PT lash adjusters and rockers? I habe stock valves cuz I was told upgraded arnt much different. Now what about other bolt ons? Imma get bigger cams now are aftermarket cams actually worth spending that money for ? What about a bigger TB? maybe a TB spacer? Even a under drive pulley, are any of them worth going for or just a waste of money, I have a 70mm turbo on 880 injectors bigger pistions hitting about 21 lbs of boost,

I don't know much about your setup or 420as in general, but I would say you need to invest in bigger fuel injector so you can run more boost. Also, look into running e85 or spraying meth. If the turbo is indeed that big, really look into getting a smaller, more reasonable turbo.
