Which would be the better power making head. A set of sbc pontiac heads done by HRD for hendrick motorsports or a set of keith craft 11 x sp cnc brodix. Although i will be using these on a blown application, still i have a chance to buy the pontiac heads with big block jesel rockers machined down for the sbc hendrick motorsport nascar application with titanium valves and hendrick valve covers to clear the larger jesel rockers and a fully ported and prepared by hrd bowtie intake manifold. It will cost a little more to get the brodix with regular t and d rockers and it will only have stainless valves and no manifold. Which would be the better choice? The pontiac heads cost $6000 to hendrick i was told with rockers and manifold several years ago . It was one of the last sets prepared by hrd for hendrick before the 18 degre stuff came out. They have only 50 passes on them in a drag monza. They ran 8.50's in a monza with 388 cubes and kinsler injectors on alky. Whats your opinion?
