rocker arm choices

[GMC70c20]

I am about ot start buy parts for my lq4. I was going to buy a set of l92's, cam, intake, headers, ect. the only thing I am going to use thats stock is the short block (with arp bolts in the rods and main caps). Because I am going to a gen 4 head I will need the offset rockers. I thought about just going with the factory one but they seem kind flimsy. the cam I was goign to run is 573/558 lift and will pproabably see 6500 maybe 6800 rpm from time to time I am unsure if the factory rockers will hold up to this. I was looking at after market rockers and I could find a whole lot that would use a factory stand and had the offset rocker. I saw a couple different one's but they were stud mounted and i dont tin kI would need to go to that extreme of a setup. I did see yell terra makes a set but I read a few bad thiing about them you guys know of any more that still mount on a stand adn will work on a gen 4 head?
