| Flow figure comparison for 429/460 cylinder heads. aluminum and cast iron Street style castings |
| It is worth noting here that flow figures are highly dependent on flowbench operator skill and integrity. Figures can vary as much as 10% from flow bench to flow bench, due to equipment variability. These figures are representative and should not be taken as gospel. Porting level and competency not to mention style also come into play here. As with all the information on this site this is here to help folks make informed decisions when putting together their engine combination. |

| Ported figures. All figures are mine except where noted These figures have been checked against the super flow 300 bench and I'm confident they are accurate |
| In our continuing effort to provide the most accurate information possible we will be updating the flow curves for our ported and as cast castings in the street head family of castings The street castings' flow numbers on this page are somewhat optimistic and will be revised as time allows. This is being done to allow more direct comparisons between my bench and the super flow models used by other shops. I want to strees that the HP potential of a given casting remains as it has always been. It is just the raw numbers that will be updated and refined. An example would be: Max D0VEs 355 CFM A-429's 360 CFM BT's 380 CFM RPMs 360 CFM TFS street 360 CFM Kaase SCJ's 400 CFM Dated Feb. the 4th 2005 |
| Revised flow numbers for latest RHP port work January 2006 |
| Note: The above D0VE castings are prototypes which require braze work on the roof area to allow additional needed width at the right hand roof / wall. This allows the port to utilise a greater portion of the upper right section of the port as it transitions into the bowl. |
