I thought about wet sleeving as well. But I read, in multiple places, that there are temp issues after. I will be driving this on the road as well and do not want temp issues.

I have read the same. Most I read about were pushing water. Only one way to do that and that is if the sleeve machine work was not done properly. I would suspect headgasket issues from a sleeve dropping. I am still researching this. Just any old machine shop won't do. Darton East had major issues years ago from what I was reading. The machine shop must have a 3 or 4 axis CNC and the tolerances are a thousandth to 1/2 a thousandth. It has to be perfect.

Right, I haven't read any info saying that using a wet sleeve has worked in any form.

Between the info out there on sleeves and the info out there on current shops closing decks has made me want to go my own route and try something different. I think our ideas on closing these decks will work, but I will just have to prove that after the build. -- Or I might never get our ideas off the ground. Depends on if I can get a machine shop with the proper equipment to work with me. Unfortunately I do not have a CNC
