Are those Yella Terra rockers safe for extended high rpm use?
They are fine as long as you set them up properly and don't go over the max recommended open pressure.
Yella Terra have two versions.
The Ultra lite pro which is rated to 480lb max open pressure and the pro street ultra lite which is rated to 600lb open pressure.
I am using these too.

Specs: 244/256 .629"/.604" 114+3 This cam is intended for 400+ cubic inch LS engines that are utilizing cathedral port heads and a stock style intake manifold (i.e. LS6 Intake, FAST, MSD Atomic, etc.). This cam will provide a choppy idle, but still retain some level of streetability. This cam has made 596 RWHP when coupled with TFS 245 CNC LS cylinder heads in a 2001 Camaro with a 6-speed manual transmission.
It has 22 degrees of overlap. Mij 239/254 has 18. Could it be that the camshaft is quite ok? Because changing the camshaft and lifters and pushrods makes things a lot more expensive.. The mamo heads even need roller rockers.
That cam isn't that different from your existing camshaft. I believe this is your existing cam?

I would figure out your PTV with your existing cam, consider swapping out to a cam with less exhaust duration and a more even split, mill the existing heads/go to a thinner gasket to get the CR up more and re-evaluate before dumping a bunch of money into a new setup.

The OP has some good options in this thread.
Keep asking questions till you decide which route to take.
I would advise to email Mamo and discuss your goals.
