This is what I have as a BOM for an aluminum head upgrade...I'm leaning toward the new Trickflow heads as I'm under the impression that the Edelbrock castings really need to be cleaned up before they can be used which adds time and wipes out the price difference... I have to be honest that I thought it could be done cheaper. This is encroaching on Blueprint engines crate motor territory after factoring in the sale of the stock/healthy Magnum long block (and the many hours of labor that I will put into the install). Any advice is welcome regarding this BOM. Trickflow Heads TFS-6141T784-C00 $1200x2 Rocker arm shaft studs TFS-61400613 $60 Cylinder head studs TFS-61400613 $200 Harland-Sharp roller rockers S72026K $900 Head gaskets TFS-61494040-040 $90 Pushrods $?? custom cam ~$450 Break-in oil, consumables $?? Did I miss anything? Would the end product be worth the ~$4500 investment? Compared to... BluePrint Engines 408CI Stroker Crate Engine | Small Block Chrysler Style | Longblock | Aluminum Heads | Roller Cam $6300 And it comes with a warranty too. Thanks for any input!
