Try to keep the roof angles the same but yes match the cylinder port with the sleeves.

Roof anglr of sleeve or cylinder ? I can keep the sleeve like that but matched all around the sleeve if i can ( not hurting water jacket also) ?

The metal gets thin so be careful making them too flat once they are raised.. Another option is pulling the liners and matching the cylinder to lower them. This will give many setup options but few people do this. A good pipe is required before raising the transfers will do anything.

Keep the angles of aluminum casting the same but open them up to match the sleeves. You don't want to do anything to the iron sleeve besides chamfer the edges after boring so the rings don't get hung up.
