Schumi, not powder coated. It was hot tanked by whichever machine shop Lindsey Racing uses when it was ported..etc. I had another cylinder head from my '87 n/a that was cleaned up the same way locally. I highly recommend bringing your excessively dirty engine parts to the local machine shop to have cleaned.. takes about 15 minutes and they usually look brand new.
I guess its sad that i actually felt bad putting such a clean part on the car..
