Default Camshaft Profiles and the correct supporting Mods

Hey guys, I'm building a Ver5 STi RA, and I will be building the entire block n heads before it gets swapped. I have a few questions concerning which Cams fit my build the best. Engine will consists of built bottom end, rotated gtx3071r .82a/r, 38mm TiAl EWG, walbro 255lph, ID 850-1000cc, Cooling Mist Water/Methanol inj, FMIC....
I was looking at the:
Kelford 199-J advert.@ .25mm 264/260 10.90/10.50 LSA110/113 8500rpms Complete Kelford Valvetrain w/ BC Adjustable Cam Gears.

My thoughts were that these Low duration high lift cams will compliment the gtx3071r very well in the mid range and hold on all the way to 8000rpms. But since I am just beginning to understand what Camshaft profile works best with what supporting mods, I would appreciate any help, and entertain all opinions.

3 times a week driven, Time Attack & Tarmac Raced on weekends. I'm looking for people that have experience with Kelford Cams, or just Low duration/High Lift Camshafts in general. The Kelford 199-J's are supposedly for rally and time attack. Im wondering how well they'll hold up into high RPM's. It says they're good through 8500 so idk... I don't have much experience in the Camshaft field yet. I'm hoping to gain some valuable knowledge outta running them

Well basically, I'm just curious how the 199-J's will run with my setup. Will they allow my gtx3071r to pull all the way to redline, or will it fall off early? After doing tons of research, i came to the conclusion that they were the best match for what I'm trying to do. I'm not looking for huge #'s. Although it would be nice to hit that 400 mark, but as long as I stay responsive as hell into the high 300's,

With the e's redline was no problem I even bumped it up to 8k because it kept hitting the limiter so easy.

Sounds like a Nice setup. What was it putting down? I almost went with the Blouch 1.5xt-r or the polka pickle over the gtx, but the gtx is just far superior. I can't wait to see what kind of #'s I get out of this build. This is the first time I've done everything right the first time. Atleast tried. Instead of just mix match any part that I find cheap. I'm not pinching pennies on this one. I plan on keeping this RA
