6" from the bottom of the smoke chamber to the reverse flow plate and at least 6" from the reverse flow plate to the first grill is the rule I follow. I divided my 4" stacks by two to shorten them up a bit and installed them at grate height as well. How about some pctures as you move forward?
Your pics show as being deleted? What size firebox do you have? If the firebox is 1/3 the size of the smoke chamber you will need at least 5 4" intakes at the firebox and 39" of 6" exhaust stacks. This is assuming a lot so more info is needed on your dimensions.
Looks like you are on your way. I reduced the firebox to cook chamber opening by 50% and cooked 2 fatties with perfect temps this past Wednesday. It cooked for 4 hours on 8lbs of lump. Yours is looking real good.

Thanks again, my stacks are what the calculator called for just cut in two.I just didn't really want to look like I have a flare stack on top of my smoker.
The stacks will only be open at one end at a time depending how I am cooking. I open the opposite end from the fire box and I can cook...
