boost and valve springs I have been looking around on here for a while and have been seeing alot of just using valve springs from Brian tooley racing and I'm getting ready to buy my heads for my car and got to thinking about what I should get. I was going to get a set of assembled tfs genx 255 for my 408ci . but git to thinking maybe I should just get a bare set and go from there. I'm looking to have potential to brake 1000hp in the future. So I was just wondering if the springs and valves that come with the tfs heads are enough or if I should look in to somthing different for them?

You should buy them bare as the standard valves have had issues at the 1000 hp level.
There are some optional hollow stem intake valves that will hold up better and are also lighter for better control at high rpm.
Are you going turbo or supercharged?

For springs our .660" lift Platinum dual springs work well with stock rockers.

Roller rockers are less stable at high rpm compared to stock rockers.
Every race winning and record setting hydraulic roller combination that we put together has stock rockers. For example the fastest NMCA Real Street turbo combination has stock rockers and has run in the 7.90's with a billet 76mm turbo.
