bbc heads.
I have BBc rec port open chambered, large valve, heads. No valve train. I have Matching offenhouser intake. These heads have 5 hrs on them then they were removed.
these heads were vacuumed tested and checked out perfect. I called GM USA and gave them the casting numbers 6272990 and they said they were from 70s to 80s vintage LS6 crate engine or dealer warranty work for rectangular port open chambered 10:25 compression ratio. Open to offers. i would really like to get rid of these.
Please make me an offer. Open to trade for what ever.
