Timing chain jumped? I'm thinking that's what might be causing mine to do that (in my case, timing gears, but all the same...) Quite possible exhaust valves are hanging open causing some combustion in the manifold. On the other hand, could be a intake vacuum leak with that high idle... mine holds 800rpm perfectly.
