Does anyone know the stock depth of the gsr sleeves? I was told when my block was built that they had to deck it alot. But I can't find the specs online. I'm just trying to make sure too much wasn't taken off.

 

Why did they have to deck it? I hope they know there's a difference in deck height between a B18c and a B16....

 

B/C it wasn't flat.

 

I dont have a Helms in front of me but you dont have to messure the whole sleeve depth. On the top of the block theres a guide to show if its in spec. It a dot about 3mm wide on the bottom left of the block I think. I'll see if I can get the specs.

 

I did it last night with a feeler gauge and the biggest one I could get in there was .016
