gm sleeves? or another company/

 

^^^yeah what sleeves are they? Who installed them?

 

They look like they could be Mr.B's sleeves but ill let mongo clarify for sure

 

These are High performance Ductile iron. Perfect for boosted and high compression apps. The ones I got have a slight underbore and a .010 higher collar. I bought the Kent Moore tool kits for 86 and 88 MM bore sizes. Very easy to install with the right equipment.

So will the honing take care of the under bore or will i stll need to be bored? What does it mean by a .010 higher collar?

 

You still need to get it decked. And honed to final bore size. Best way to do it if you ask me.

 

My sleeves are similar but from a different more well known company, cost 150 to have it decked and honed to my diamond pistons, my sleeves are about .002 thicker than stock. Like cmiller said, best way to do it.
I have bought like 15 things form mongorat. Always a good buy and a good part.

 

Yes these sleeves will need to be honed as they are only slightly under size. The extra deck collar height was recommended to me by Mr B because of the inconsistancies from block to block.
