NEW Updated ports for 2009 !!! Better Power, Better Flow !!

The Best Conventional style big block Chevy head available in this price range!

Yes this is the head everyone has been talking about, . . serious flow, great airspeed, very good coeficient of discharge, . . VERY good power!

We have done back to back flow tests with other heads in this market & price range. Heads built for 540ci to 632ci drag race or marine race applications and even though some advertise more flow, on our bench the RFD / Victor flowed the best with the best air speed and velocity profile, . we think it's the best and we know you will too.
