    Deogi2 GSX - #380

    Hi, All back together and first start up after having heads redone. Wound up replacing push rods and rocker assembly too. Still need to power time and didn’t go for a test run yet as streets were wet. Compression up to 170+ in each cylinder. Bad #3 was 115. Vacuum up from 18.5 to 20.5.
