I may not need it, the cold specs are dead on, (Feeler gauge needs to be able to slide through with 'some' resistance, correct?)

I'll test the hot specs soon enough, but would they be off..?

Either way, when running the motor, if I rev it up a little bit, and when I let off (And ONLY when I let off) do I hear a noise coming from the area of cylinders 5 and 6, it sounds like one of those spring door stoppers, but higher pitch, I'll try to get a video of it

I still need to do the timing, and brakes... brakes too...
