New Scorpion Performance Roller Rockers?

Anyone have them installed yet? Can you give me some input on how they are? Any gains? Do you have to change valve springs on a stock motor when you install them? Thanks.

Some guy with a corvette had those Scorpion Rockers placed in his ride.Something went wrong with one of the rockers and they were chewed up. He call the company,and they replace the rockers for free.Their is a thread in here about them rockers.

Almost all of them had cracks. If I had to guess, from the pic it looks like inferior casting is to blame.

I didn't mention it in the other thread, but it does look like a casting break. I posted the Crane photo's because it looks like the Scorpion's don't have much material in the area either.

I would pull the head and check for piston/valve damage. He does not even know what ratio he got, with his cam he could have had issues with piston/valve.
