Valvetrain and camshaft selection

Valvetrain and camshaft selection
I'm about to start my build within the next few weeks. My shop needs to know what type of valvetrain I'm gonna need to have installed on the GSR head.
I've singled it down to a few brands. I'm leaning towards Supertech for the valvetrain minus the valves themselves, which will be Ferrea 6000 series. However, I wanted others to give me feedback on the Supertech's and high HP setups(350whp+). I'm not gonna cut corners here, I'm looking to have the finest street setup around, however if certain expensive brands are not necessary, then I see no need to have them.
Another big issue, which could deviate my total costs by 300-400 bucks is the camshaft selection. I would like to have the most efficient set of cams for turbo app. I need input on this, and perhaps some basic results of those switching from one cam to another. I know GSR's are the best to have for cheap, or Type-R's..but if I'm willing to purchase Skunk2's or CompCams, or even Toda's for that matter, I'd do it if I knew there was a better powerband to be had from them. Somebody fill me in with some good info, and I prefer some type of results or data to back up your claim, as heresay is useless to me.

Most use R cams, use them and be done with it.
And 350whp is not a serious street setup that requires headwork, can be had on a stock block with 14lb boost.

Re: (96 GSR-T)
GSR cams will work fine for your power levels, there are better places to spend that money. any of the major springs/retainers are good. i use REV because they were like 250 for the set. stock would work fine unless you need to rev higher than 8200 for some reason. and upgrading the valves is pretty much overkill too.

Re: (ndogg)
why wouldnt you just use a full ferrea valvetrain? id look at ferrea, skunk2, omni and supertech makes good valvetrains as well. and yea, id use gsr or itr cams- depending on your budget.
