FWIW, my Eddy 84cc heads didn't flow their advertised #s OOTB, but they did respond pretty well to bowl & port work.
(Mine is a 440-port motor, not a Max Wedge deal).
I'm an aluminum fan when it comes to heads, for weight, port-work & repairability. I use the FelPro composite (1009?) gaskets, not metal, and run double springs.
