Just got my cylinder head back from the machine shop today and they told me they cut 0.006 off.
The shop recommended me to not mess/replace the valve stems and to not clean the carbon on the valves. I've talked to a Toyota Master Mechanic and he said he would clean them up for $200 but even he seemed to have the "you don't have to" attitude. Should I go ahead and have him clean the valves or am I being a typical over the top anal mudder? If it isn't too hard to mess up I figure new valve stem might be a good while you're in there thing to do.
NKP Garage on YouTube as well as OTRAMM used a tool similar to this to disassemble the valves:
Amazon product ASIN B000F5ECUY
The shop pressure checked the head and it was "in spec" but now im a bit skeptical because according to half k cruiser, my head is warped to the point where its "out of spec".
Thanks!
EDIT: Looks like the head came back with an extra dent on the exhaust side...
According to this post, my head is toast..?1) FSM states 0.15mm or 0.0059 in of warpage maximum. Technically this should answer most of your questions. Your head is toast !
