I just had my head milled and was told to get a shim. Head was warped 0.028" milled 30 off it. Said to get a 0.020 shim which I cant seem to find. He also didnt have the specs in his books to say if 30 was allowable with tolerances. Shorter head equals higher compression which needs more octane...

So after healing up from a fall- I got the head to the machine shop today. Its out 0.028"
Machine shop cant find specs on allowable milling and suggested a block shim.
Is Cutting 0.030 too much for the 2.8L heads?

Is there a shim available from somewhere.

Thanks

Ok so on tear down mode. I don't see the reference marks for cam timing.
Can't seem to get the serpentine belt from around the crank pulley either
While this is torn down what else should be replaced. Water pump, idler pulleys thermostat?

Thanks
