I'm getting ready to put the head together and started wondering what rpm and power the stock rockers can handle.

set up is

GSR head
CTR cams
stock size Ferrea valves
supertech springs and retainers (the stiffer ones)
10.5:1 pistons
11k rev limit
6765 turbo

car made 851 last time it was on the dyno

Thanks in advance for the help

 

Don't worry, something else will probably blow up before the rocker arms do at that power level.

 

gee thanks lol.

anyone have input or info?

 

Is it making its peak power at 11k? If not then why rev it that high?

 

My 2 cents...

HP isnt really gonna affect the rocker arms. RPMs will. The force is the same at 200whp vs 800whp. They're forged. They're plenty strong...

 

The power is climbing at 10k, the limiter is set to 11k for the track.

I agree the rpm will affect it the most, just trying to figure out what the limit is so I dont break em.
