Bulletproof....that's the best way to describe this pair of heads for your LB7. Featuring fully CNC porting and screw in torque lock injector cups, they've got all of the bells and whistles for a full engine build.

THE PROCESS: Heads are first jet washed in a high pressure spray cabinet to remove oil and dirt, then glass beaded to remove carbon. Next they are checked by magnafluxing, (cast iron only) or pressure testing. They are visually inspected for defects that would make them unusable. Valve guides and seats are removed as needed for porting.

Port development is accomplished using a superflow 600 flow bench with a computer recording all flow measurements. Many things are considered when designing a cylinder head Port; air flow is only one of the things to think about. Another major concern is port wall thickness. Anyone can get a head to produce high flow numbers, but if doing so leaves the port wall too thin, the casting will crack. High performance diesel heads are more prone to crack because of the thermal shock experienced by excessive intermittent or long term exhaust temperatures.

The porting is then performed using a five axis CNC cylinder head porting machine with CAD/CAM software specifically designed for cylinder head porting. CNC porting brings unparalleled accuracy to head porting with each port flowing the same. This helps balance the power that each cylinder produces, making tuning easier.

New high strength alloy, heat treated iron based valve guides are installed. These guides are heat treated to Rockwell 22 "C" Scale, which produces the ultimate in wear resistance. This is far superior to original guide material, including bronze. The guide incorporates a spiral grove inside the guide to hold oil and aid the lubrication of the valve during engine operation.

Guides are then honed (not reamed) to exact size using a diamond honing mandrel. Diamond abrasives allow for consistency of size, surface finish, and bore geometry with no variation from guide to guide. The guide size is then verified using a valve guide bore gauge.

As needed the head receives new premium valve seat inserts made from a true nickel based non-magnetic material that was developed for extreme operating conditions. Next the head is treated to a multi angle valve job to help maximize the flow of air in and out of the head. This is accomplished using a Serdi 100 guide and seat machine. Serdi uses a solid carbide straight shank pilot. When inserted into the valve guide, it simulates the real valve stem during the centering process. This guarantees the valve seat is finished for a perfect valve to seat match.

Using CBN or Diamond tooling, the head is given a new surface. With a berco milling machine, Industrial can control the surface finish to accommodate different head gasket types. For example, MLS head gaskets require a very smooth surface finish. Finally, the head is jet washed dried and assembled with new valve seals and new performance valve springs.

Simple, Basic and NOT expensive
Color: Black, Style: coffeemaker
Not Fancy, Not Complicated, Not Expensive. What else do you need in the morning. Replaced the same model with a new one as my old one broke after more than 15 years of faithful service. Takes 11 minutes to brew 8 cups of coffee, which BTW is really only 3.5 cups of coffee in a real mug. Yes, you can set it to start automatically in the morning. Thank goodness for Amazon same day delivery or there would have been chaos the next morning.

A week with this guy and it has been great! Coffee is brewed quickly! Easy to clean and no mess pour! Size is perfect and exactly what we needed. Black of course is always the best color!

Good value. Decent coffee maker.
Color: Black, Style: coffeemaker
This is a decent pretty basic coffee maker. Nothing fancy but it’s programmable and has sneak a cup. That’s all I really care about. I was concerned after reading some reviews about the coffee tasting plastic and leaking. I’m glad that I have not experienced these issues. I bought this because all of the $70-$100 coffee makers I’ve bought die after a year or two anyway. So far so good.

It’s fine, very basic- light during brewing doesn’t work, but it still brews a good cup!
Color: Black, Style: coffeemaker
Sadly I accidentally dropped my coffee pot into my sink trying to wash it and it shattered the entire bottom, so I just bought a similar one, same brand. It works fine, but it doesn’t work as the instructions say. Supposedly when you push the clock button to brew it will give you a green light on the left upper side, and when it’s done brewing it will have a red logo on the bottom right side. I cannot get it to give me the green light for brewing, but if I just hold the clock button down, I’ll hear it stat to gurgle and then it brews. So that part is definitely (at least on mine) not functioning properly, but I don’t care enough to return it and be without coffee another morning, and B&D is always a decent brand. I have a $2800k fancy espresso/latte/cappuccino maker that grinds fresh beans and I use the plain old coffee pot way more because I drink too much coffee to make cup after cup, I want the whole carafe. Besides that one faulty light, it works like any other $35 coffee pot, no frills, and it gets the job done.

Simple, Powerful, and So Much Easier Than Traditional Vacuum Sealers
Color: White
I’ve used traditional vacuum sealers before, and this handheld one is honestly so much easier to work with. The design is simple and compact, and it takes up almost no space in the kitchen compared to the larger machines. One thing I really appreciate is how easy it is to operate. The one-button design makes sealing quick, and the suction is surprisingly strong for such a small device. It removes the air from the bags quickly and seals everything tightly. The bags themselves are also really well made. The material feels thick and durable, so I don’t have to worry about them puncturing easily, even when storing things with sharper edges. Being reusable is a big plus too. Overall this has been a really convenient way to keep food fresh longer without dealing with a bulky machine. If you want something simple, effective, and easy to use for everyday food storage, this is a great option.
