I guess I know less about this then I thought I did.....So actually making the ports larger is a big no no...If I am understanding this right only remove material from the outside or the sleeve without inlarging the ports...won't this thin the wall of the sleeve and create a hot spot in the sleeve??

Thanks Again for the help because I can see that I was heading in totally the wrong direction....This is kind of a spare engine and I don't mind screwing it up but I would like to see it run after the mods are done..

Oh and Sman...I asked these questions to get info not to get talked to like a jackass so if you can't reply in a respectful way keep your non-informative comments to yourself.....ASS!
