I have the following mods on my C6 LS3:
A&A supercharger with 3.4 pulley

Longtube headers 1 7/8

methanol injection

I would like to get 800rwhp out of my ride and don't know what valve springs and pushrods I need to upgrade to in order to support this kind of power. If anyone could point me in the right direction I would be greatly appreciative

If you have and plan to retain the stock cam the ls9 valve spring will be nice...
Can still retain same push rods with above springs while still been acceptable to the stock lifters...
