My head builder called today. The 153 head is done!! New studs, guide plates, Perfect Circle valve seals, stainless valves, new keepers, stainless retainers, new springs set to proper height and tension, lumps installed, and a good street port job. The lumps are the newer Max Flow variety.
Intakes flow 163 at .200, 190 at .300, 220 at .400, and 265 at .500.
Exhausts were 120 at .200 and 210 at .500. He called me on the phone to give me the numbers and I don't remember the exhaust numbers for .300 and .400.
He also gave me numbers for .600, but I was too stoked already and can't remember them!!
He always does some extra stuff like cleaning up the oil return passages and cleaning up all of the excess flashing. He hadn't ever done a set of lumps and he was tickled with the results!! Bridges Machine is the place to go in the Nashville area. I've never been disappointed with Jimmy's work and his help Chris is top shelf too!!
