Highest flowing sbm heads?

I'd do the Indy 360-1 top end package with port work done on the heads and intake.

I like the flow numbers Hughes posts for the Victors better. My last issue with the Victor heads is the exhaust. As most know only tti makes headers for the 67 Cuda and the Victor heads, I think. I hate the idea of losing my power steering. What steering option does a guy have if he uses Victor heads and the TTI headers? Is there a rack system that fits or am I limited to manual steering box?
