Depending on the flow of those heads a 90/90 would probably be the better investment over rockers. Crane, Comp, YellaTerra, Harland Sharp...they all have cheerleaders and detractors.

One thing I very rarely see mentioned with regards to the stock rockers. They were designed for the stock valve train, with fairly low pressure springs. They have a fairly wide wipe pattern, at least mine did. Some even wipe towards the side of the valve. Now boost the spring pressures and two things come into play. First, guide wear will increase unless you have a narrow wipe pattern, and with higher lift the stocker's wipe pattern gets worse. Second, you lose lift with them with higher spring pressures as they are not very stiff. So you can run the stockers fine, but there are trade-offs in doing so in my opinion.
