I think no relation between 1000hp and strenght of the rocker, I would said That I will be using Triple Springs with 100 kg of initial charge. The header man (who improve the head ) said that normal rockers will collapse, or head will be broke if Y dont put rockers together. and another thing is that I need more lubrication, because oil never will go up throw the original part, because we change pushrods, with bigger an with no lubrication.
Tanks for your help.
I sent pics of my head.

That is one the nicest prepared heads head I have ever seen. It looks like a work of art.
Do you know that spark plug adapters are available ($10 each) to convert from 18 mm to 14 mm plugs.
Some NASCAR engines use spray bars to cool and lube the top end with oil.

One more question, I can´t figure what kind of cylinder head did you use in your drag? Can you tell me?

My cam is a hydraulic flat tappet for street/strip use.
It has .534" valve lift.
I used the Comp 990-974 spring.
Installed height is 1.635" which gave me 115 lbs on the seat and 310 lbs open.
Your valve springs will depend on your camshaft profile and the closed and open pressure is usually called out by the cam card that came with the cam
Did the cam supplier specify the spring specifications needed for your cam?
My head has 2.02" intake valves and 1.60" exhaust
The head flowed 212 cfm on the intake and 179 cfm on the exhaust both at .600" lift
