Can anyone ever give some Information on a thread for conversation without criticism. I am sure the OP doesn't have an aluminum block 340.. I was just giving all some info that not even you knew.
This was your quote ending in "ever" wasn't it
"You don’t leave the sleeve proud on a block that take a straight sleeve. Ever." Well I guess you are wrong with "ever"
I am 70 years old and I myself am still learning. I would believe Steve before anyone . He installs sleeves in many different engines I have seen with outstanding results. Nitro/top fuel, Methanol, Aluminum Hemi's and the Chebies. After welding the blocks back together.
Steve is always surfing this site but never comments. He told me he doesn't have the time in the day for some of the nitwits so he leaves it to me. I have all the time in the world . LOL
Maybe this will help you relax. Lay back and have a cold one.
