I recently set up a group buy for fellow SHO enthusiasts for having our intake runners Extrude Hone'd. I am very pleased with how my runners turned out and I thought everyone would like to see the pictures as well. Note: I am also grinding the casting marks away on the exterior of the runners and the rest of the intake. Gasket matching is being done as well! Sorry, I forgot to take "before" pictures.
