NO proform rockers!
Look into scorpions if you want to go cheap, I have used a bunch of them with no trouble.
Those springs will handle that cam and much much more. I have been very satisfied with them and been up to 7k with them several times with wilder cams.
You're going to have trouble finding self aligning rockers that fit 7/16" studs because the larger stud rockers take up more room in the valve covers and are more of a challenge to fit in centerbolt valve covers. Not too much issue though plenty have fit em under there.

Stock studs are 3/8" at the top where the rocker rides and the poly-loc goes on. The part of the stud that screws into the head is 7/16" either way. If you want to use the stock studs you need 3/8" rockers.

DO NOT USE ANYTHING OTHER THAN GMPP SPRINGS.
I didn't listen to my own advice, but took the advice of a mechanic who was wrong...FOUR TIMES!!!
DO NOT USE MANLY SPRINGS. I RECOMMEND THE SPRINGS THAT COME IN THE KIT.
Been there, done that, made mistakes, offering free advice. Take it or leave it.

The LT4 Spring accommodates for more lift than the hotcam w/ 1.6rr's. Thousands of people have used them and I haven't personally heard anyone having LT4 Springs fail (though there maybe a few, but I'd have to search for it and know more about there setup to even know if it was the springs fault)

I'm not a fan of the lt4 springs but they will work. They will be pretty much maxed out with the hotcam but they will handle it fine. I would not dare use them with anymore lift than the hotcam has, they are close enough to coil bind for my taste with that even. The open pressure is just fine on them but the 100# seated pressure leaves something to be desired imo. Also be aware, stated rocker ratio is not always what you get and will changed based on geometry and rocker brand.
