Roger,

I removed the tubes from the 392 heads on the engine I just rebuilt.  They
were really baked / corroded in place and the only way I was able to get
them out was by tapping them out with a punch from the exhaust valve pocket
(valve removed) to the outside.  I can't imagine how in the world you'd get
them out of the heads are still assembled and on the engine.  The IH shop
manual shows a technique where they're being removed with a round file.
This might work on a brand new engine, but it sure as heck didn't work on
mine.

Maybe you could drill them out???

Good luck,

John L.
