The better question is will they cause lag if I use them for building material? The reason I ask is I use the gauges instead of glass on a lot of my builds because they can be broken down and picked up and also like the way it looks in my texture pack.
I have seen people say to not use the coke oven and blast furnace bricks for builds for this reason, I suspect it's the same with tank block.
