410 LA small block will not rev past 6000

He said above he had 2.055 valves installed and then did some work on the ports. If it was good work the heads will easily work to 7000

I was reading all that too and saying nah.. 2.05 eddy's ported, not destroyed, should be plenty enough for 7k @410cid.
I've had 410 cid sb with balls deep ported j heads get into 7200 rpm no problem...Though the solid roller helped too .lol
