Would either one of you have the tool to ream the counter bore so my sleeves have the correct protusion. If so would it be possible for us to hook up to fix my block. (I'm in central maryland)
I took my block to a machine shop to have it cooked, cam bearings installed and the sleeve protrusion checked and the guy (owner of the shop) said they were all .007 to .011 protusion. I told him the book calls for .002 to .005, he said oh it's more important that they are all close to the same protusion. I agree with that but I want them to be within the .002 to .005 and with no more then .002 difference. The guy seemed to not want to be bothered with me anymore so I took my stuff and left. thanks.

i had the same problem with my super m block. the sleeve stuck too far out of the block. the machine shop surfaced the top of the block to get the sleeves back down. i would avoid machining the counter bore, if you ever have to re sleeve the block, there way be a problem with the counterbores being too deep and the sleeves sitting too far in the bore.

If the sleeve standout is TOO great, machining the tops of the sleeves (rather than the block)MAY be an option.

You should contact Mark at the Kunkle Service company in Bel Air at 410-838-3344. He may be able to machine the top of the new sleeves. They do good machine work and have been in business for the last 75 years. All their machinists are ASE certified. You can take your block to any of their stores and they will ship your block to the Bel Air store where their machine shop is located. George in MD can it too as he has a machine shop. Call George at 410-452-5255. Hal

P.S....

Have you THOROUGHLY cleaned the sleeve conterbores, then installed the sleeves WITHOUT the "O" rings, carefully clamped them down with a couple of short bolts and washers for each sleeve in the headbolt holes, THEN measured the "standout"?

It MAY help to swap the sleeves from hole-to-hole to find the best match.

i agree with bob. .011 is a little much. .005 sounds good.glennster said "the machine shop surfaced the top of the block to get the sleeves back down" . its the opposite, the more you surface the block the higher your standout will be.same principle as a stepped flywheel. you need to remove the same amount on both surfaces.
