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.

Good stuffies for my Goldie.
Set name: Stuffed Animal Dog Toy Set (5 Pcs)
My dog is a heavy chewer so I don’t expect things to last long with him. But with that being said, he actually doesn’t go too hard on these stuffies and loves each and every one. Will they stand up to aggressive chewing? No they are stuffies. But for this price and for the quality, they are worth it for sure. Sometimes they don’t always squeak but I’m ok with that, because the constant squeaking can drive you crazy. I have a golden who can shove 3 of these in his big mouth but truly, one fits just fine. They are good sized for big dogs, it’s just that mine prefers to have his mouth stuffed like a chipmunk. He loves these stuffies and we will be ordering more for his endless toy box that I didn’t know I needed!

Good for puppies or dogs with little to no teeth!
Set name: Stuffed Animal Dog Toy Set (5 Pcs)
Good for the most part. Definitely not made for a heavy chewer! My dog shredded all 5 plushies within a couple days. Lol She got a hold of 2 them the first night and we woke up to a plushie crime scene. Fluff was everywhere and the squeakers were in pieces in the middle. The toys were unrecognizable, and no one could possibly have identified their intended animal shapes. Our silly girl was laying next to the massacred toys with what could only be described as a prideful grin.

Great assortment to keep the dog running
Set name: Stuffed Animal Dog Toy Set (5 Pcs)
My Jack Russell Terrier mix is madly in love with these squeaky toys. Every morning when he gets up he demands to have at least 4 throws of these as part of his morning ritual now. He loves them, and they seem well sewn and will last him quite a long time (but he has only a couple teeth), and they are washable which this dog mom likes. A good investment for my JRT mix.

Doggo Fun
Set name: Stuffed Animal Dog Toy Set (5 Pcs)
My dogs like these they were just smaller then I thought. They are made for medium dogs. Our big doggo can put the whole thing in her mouth. The squeek isn't too annoying and the overall make of the toy is nice. If you have a doggo that likes to attack and get the squeeker out this toy isn't a match for them. They will distroy it in minutes. If you have a dog that loves to just carry stuffies then these are good for them.
