I'm looking at purchasing a block that the deck was closed in like the H22 and H23. It is a D16z6 block with what looks like stock sleeves, possibly ductile iron. I'm not sure. On the outside the deck is closed with aluminum. Would this thing hold high boost levels. I don't have a camera, so i have to give you the best description i can.

 

is it a block guard?

 

AEBS and DART sleeves are the only sleeves availble for closed deck on d-series last time I checked.


otherwise you got a block guard

 

Darton makes a setup also.
