The Jesel Sportman shaft rockers are good to 900 lbs. open spring pressure. They cost more, but it is more likely that you will have to buy them only once.

Yella Terra has their Platinum Series rocker arms for high spring pressure applications. They are a "wide body" arm for even greater strength and resistance to deflection.

I reallydo hate to see people waste money on supposedly "top teer" parts.....if you want to talk aggressive, on my 408 that I spin to 8,000 rpms I am still running the factory rockers with the trutton upgrade and plan on doing so for years to come....imho until you get to the point where you NEED to, spend $1,500 + on a set of Jessel rockers and have it done....when I get to the point of turbocharging mine and spoiling to 10,000 rpms or more these are what I am hoing to buy...til then i stay with the upgraded stockers

A ????
Looking at the failed rocker, it appears that the area next to the trunnion has been ground for spring/retainer clearance. Y/N??
