Any updates?
I would think that the small iron-aluminum-aluminum boundary layer would help to conduct heat away from the top of the cylinders vs the iron-coolant-aluminum interface.
...
From a structural sense, the block guards make alot of sense. From the little research I have done so far, it appears that they are not as strong as sleeving, but reduce cylinder movement in high HP builds. Some people are claiming that they do reduce cooling in the upper part of the cylinder, which would not be good. Nonetheless, both the SuperTech and KMS block guards have numerous small cooling passages and, of course, they will need to be drilled out with much larger cooling passages to match those in the head gasket.
Another solution could be to only use portions of the block guard at structurally significant locations. For example, instead of completely surrounding the cylinders and then drilling holes, perhaps weld in a 2" section on the two opposing portions of each cylinder that are aligned with the rotation of the crank.

If I remember correctly, the coolant contamination made it difficult to do this and took the welder quite a bit of time.

why did you use rev-up cooling system that passes coolant to the heads at the rear cylinders instead of the HR that passes coolant to the exhaust valves??? are you planning blowing the headgaskets out the rear of the engine??? just an observation... and the VR38 deck does have holes to alow coolant to the heads through the gaskts... oil cools the combustion chambers coolant is around the cylinders for quick warmup for emissions... I think that is all of my 2 cents...
