The iron ram heads from Hughes are what...the EQ heads? The EQ and RHS head are the best bang for the buck small block out there staying below 600 hp. The RHS even has the advantage of coming in a version that is the magnum design with the provisions to use LA rocker gear. Both come drilled for either the magnum or LA intake.

I can tell you that both the 2.02 RHS and EQ head outflowed the OOTB Eddy head on the bench we use. We also found that rubbing on the same spots on the EQ has we did on the RHS heads, the EQ's actually had a little better flow in the mid lift area.

The only knock I have is like OE magnum heads, the seats need cut and the guides trimmed to run any valve spring other than what will limit you to about 525" lift...
