If sleeving isnt done properly then you will encounter issues, it's not worth the risk in my opinion .

I build most of the motors at Ptuning , I can tell you the factory sleeves are the same thickness as the tc block from looking at the motors torn down. We have taken that block past 600hp.

That is a very good news for me
