When it was time to buy your new set of heads, you probably didn't have the added income to afford the CNCed version. Well, now that isn't a problem. High Velocity Heads can take last year's head and transform the ports from the as cast versions to a fully CNCed piece, including intake manifolds. HVH improves on the Edelbrock Victor Jr. line by offering a 5-axis CNCed version that smoothes the complete intake track and runners. They claim up to a 57 CFM increase with their port work.
HVH also offers an aluminum version of the popular double hump heads that also come fully CNC ported. The heads come with 2.02 stainless steel intake valves and 1.60 exhaust valves that is sprung by beehive valve springs. The intake runners come in at 175 CC and are designed to work with virtually any intake manifold.
