H/c/i Questions And Opinions

I ended up getting TFS 170 heads and I have a few follow up questions as I piece together the rest of the package...

-I bought the assembled heads which have the 1.46" valvesprings. When purchasing roller rockers, should I consider upgrading to the larger 7/16" studs and purchasing corresponding rockers, or will the included 3/8" stud be ok given the capabilities of my valvesprings? As I mentioned before I may at least explore the idea of a custom cam. So I guess I want to know if I should worry about the weak link--the springs or the studs? (Or am I being crazy?)

-As for the roller rockers, is there any stud mount rocker that is exceptionally good or bad? Ie something I must have or must avoid? Steel vs Aluminum? Any brands? I've noticed the Trick Flow 3/8" set as well as the Comp Cams 17043-16 set. Both are aluminum and bother are 1.6 ratio.

-For lifters, are the FRPP ones offered on Latemodel Restoration good parts? They offer a standard version ($123) and a performance version ($199). Is there any real life difference? Any other brands? I assume I should change these when I do everything else, but if that's not the case let me know.

-For the timing chain, is the Comp Cams Magnum chain listed on LRS ($40) for some reason inferior to the FRPP ones which cost more than double?

Thanks

Interesting. I was figuring this combo, based on what we've all discussed here so far, would be around 300hp. I've been clear that I don't really care about the number so much but 30hp less is quite a bit--10%. Is the Cobra intake that much of a choke? I already have it and really want to keep it, but if it's going to hurt me that much I'm not so sure.

Anything else missing from your combo? Injectors, MAF, custom tune?
