396 LT1 miss at operating temp.
Ok, well I've only got on problem with my 396. Once it reaches about 190 degrees, the engine begins to misfire getting proressively worse until it simply dies.
Any help or suggestions are of course welcome

Opti and O2's test fine in all areas.
Opti was even pulled apart and checked off the car for any little bits of crud that might fowl the optical sensor.

How long has it been running with this set of heads?
Valve guides to tight maybe?
If-If they are that would hold valves open untill it cools off and maybe enough to stall it if enough valves stayed open.
