Here are some more photos. Installed O2 sensor bungs in the headers. I bucked up for a wideband sensor too. I still plan to use pickling paste to clean the heat stains, then the engine heat will turn the welds and tubing all the same color. I think that's what will happen anyway, I've never used it before.
Touched up the exhaust valve job. I use the shop made stone holder on the angle grider to rough then the proper Sioux stone holder and driver to finish. Left intakes alone because they look good.
Checking spring force with shop made checker. Isky 205-D are nice parts. Consistent force and shot peened and ground dampers.
Measured all the spring heights and selected shims.
