Got the head back from the machine shop the other day. Looks good, most of the work was done on the intake side, with a little bit of smoothing out on the exhaust side. For those wondering the new springs came from a nissan KA24. Head bolts were not changed out. For those curious what the torque is with the manual spec 24.5 nm + 180 degrees. It amounts to only about 35lb ft of torque or close to. I increased this number just a tiny bit.
