Rather than start a new post I thought I'd ad on to this one as the content is similar to the Vortec heads I removed from the engine this thread was about.
A while back a friend of mine picked up a 350 Vortec for next to nothing in the hopes it could be brought back to life as I did with the motor currently in my car. For the price, we reasoned that even if the short block turned out to be junk (it was), that the Vortec heads would be well worth the price paid for the motor. Prior to tearing down the short block, my friend gave me the heads to see what I could do with them...…...this is what I was presented with.

I was less than optimistic about the outcome of this project! However, I reasoned that it cost basically nothing but some time to have a go at them and see what would come of them, so I proceeded.
As is my usual routine the heads spent a considerable amount of time in my electrolysis tank getting rid of all the rust.
I don't know why it still surprises me, but the results of the electrolysis were excellent as they usually are.

Threw some paint on to keep them from flash rusting afterwards.

Gave the exhaust ports a quick clean up.

Cleaned up the valves and lapped them in.

Unfortunately after putting the effort into these heads, we tore the short block down to find out it was junk......now the owner is thinking of going a different direction with his engine plans and is thinking of selling these heads along with the dual plane manifold he picked up to go along with them.
