Pitting in Combustion Chamber

[Skeeter65]

I saw a set of bare C8OE 6090-N heads for sale but they appear to have significant pitting in some of the combustion chambers. Are these salvageable and or worth putting work into vs a set of Trick FLows whenever they are back in stock?  They would be for a 445 build. Just looking at head options while I wait for my block to be machined.

There has to be better condition heads available.
I would pass on those - even if free.
Those will need a lot of work.

Any of the aftermarket aluminum castings will be money well spent.

If there's pitting on the valve seats, they're scrap.  If the seats are good, then you could run those.  The pits won't hurt anything.  People have experimented by dimpling the combustion chambers, and runners.  Golf ball theory.  If they're bare heads needing work, you might just want to go the aftermarket head route.  Sometimes you just have to pull the plug.

  Serious RUST , I would pass too.

That is what I was thinking as well. I thought they would be a good deal at $600 until I saw the pitting. Thanks for the input guys!

When porting a head with those pitting issues, I always find the rust goes deep, much deeper than needed to port the chamber or intake runner.  I would pass on them, personally.  Joe-JDC
