Aluminum Rockers?

[Pillow]

Does anyone out there make aluminum rockers for a T1 or T4?

I was in the junkyard last weekend and playing with some Ricer cars motors... They use aluminum rockers with tee tiny valve stems and springs with ungodly redlines. Why can't we have the same luxury?

The down side is maybe with the pushrods the rockers need to be steel as to remain strong over extended mileage.

If Oliver now has titanium pushrods why not titanium rockers?


Thanks,
