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.

Best soccer ball with tabs for dogs, must buy.
Size: Large Size 3, Color: B-Colorful Blue
My dogs favorite toy of all times. If your dog likes playing with balls get this for your dog. The tabs are the best addition. My dog chews the tabs off but that doesn’t stop us from continuing to use the ball.

Colorful, easy to inflate, durable. Arrived quickly and excellent condition. My dog really enjoys her play time with it. I have a mixed breed border collie and she has been giving this ball a run for the money! My dog is 30 lb, we ordered the extra large size.

Dogs only toy that has not broken.
Size: Extra Large Size 4, Color: Rainbow
I've ordered them in 6, 7, and 8 inches I think. She is an aggressive chewer who had destroyed every toy I've given her. But not these! She has chewed off every strap which I've promptly taken from her to avoid her eating them. But the ball itself is chew resistant! I use the small 6" one to play around inside with her and the larger ones to play outside. My puppy absolutely loves playing "soccer" with these. Worth the money IMO.

Pup loves this!
Size: 6 Inch, Color: Red
This soccer ball is so cute. My dog loves to play with these. The straps are durable, easy to pump up (they come with a pump), good value for the money since they tend to last awhile, at least for us. The straps are durable but could be an issue if your dog is an aggressive chewer. They stay pumped up for quite awhile and just need to be topped off once in awhile to keep the bounce there. We keep them outside even in the winter and they do just fine. HIghly recommend as a good play toy.
