What? No porting?
Went ahead and did the Comp rocker arm trunnion upgrade today.
Once you've had a stock rocker fail, by dumping it's needle bearings out, locking the rocker down and ventilating a piston via force, the trunnion kit is an always-do upgrade.

You ever had a late rocker spit out the needles?
In respect to the rectangle port, offset intake rockers, or just late model cathedral port?
I've seen and experienced 07+ cathedral port bearing failures. Never on a 07+ rectangle port head.
How many iterations were there? I was thinking cathedral port circa de 2004. That was V2 from what I understand.
From my research, something changed in 2005. But I also frequently use 07-13 243/799 truck heads and always change the bearings out. I will say, the non-captured needle bearings are the same as 97-04 rocker assemblies.
