Chinese 12valve head comparison
Had to get a new Chinese head as my OEM 94 head was cracked in 1653 places. Surface finish - rough, the head was straight but surface finished could be felt with finger, pretty rough, but I think OEM comparable. Would probably be fine with OEM graphite gasket. I had it decked 4thou for finer finish as I’ll be running MLS gasket. Valve seals are top hat style with unknown material. All the valves sealed when pretty tested. I’ve ordered some mahle viton seals. Exhaust spring appears to be upgraded/different than OEM. Spring retainer also finer machining, but thinner than OEM. I’m assuming that exhaust springs are +60 but I have no was to test it. Intake spring appears to be the same. Should I upgrade my intake spring to the same cone style? Will be running 3K VE pump.

@Robert Winkworth Still has plenty of power to mow and wasn’t smoking out of the fill tube. I’ll just run it till it quits I guess. Got it in a trade a while back.
Piston protrusion 6.7l
Along the wrist pin, front to back, was getting between 0.010-0.18. Dial was checked for zero between each cylinder. For every cylinder, the front measurement was less than the rear. I am assuming this is normal. From side to side at max tilt, ~0.020 was my highest measurement. Next check will be valve recession. Thanks, SW

Anyone have a spare harmonic balancer for a 6.7? I'm located in ontario. Will pay to ship.

@Mark Livingston I am going to buy one. Money is a little too tight to give mine away. I may need it a little longer before I can afford this one, or I would have given mine up.
