Ai 260cc CNC'd GM 823 L92 Cylinder Head Package. GM's #823 rectangular port casting has decent potential out of the box. Our 260cc Budget CNC option is a great choice for guys who would like to realize most of the potential gains available with the 823, but are not inclined to port the casting to its ultimate potential.
Valve Angles and Canted Valves. Intake and exhaust valves are placed at angles relative to the piston centerline for reasons of flow and fit. If the valves are "straight up" (in-line with the piston centerline), the flow area is limited and the head needs to be much taller to accommodate the valves.
A separate intake manifold measuring system consisting of a jig set and calipers determines the proper width to suit each engine. This intake manifold resurfacing fixture has been under development since late 1999. I can provide intake manifold fitting and re machining services for any V series (and many other) manifolds.

On average, cathedral port heads have smaller runners (in terms of volume). Until recently, the largest intake valve you could fit was 2.08 inches. By normal standards this is considered quite large, but not compared to the 2.20-inch intake valves in an LS7 head or …
The Dart casting is produced with, and must maintain a 60cc combustion chamber, a 2.02" intake valve and a 1.60" exhaust valve. Machining the valve guide bosses for seals and machining the gasket surfaces is permitted. The addition of screw-in studs, guide plates, valve spring seats, valve seals, poly-locks or jam-nuts is permitted.
The valves and seats in an internal combustion engine play a central role in engine breathing, compression, performance and longevity. It doesn't matter if an engine has two, three, four or even five valves per cylinder or if the engine is gas or diesel because the valves all do the same thing: they open and close to allow air into the cylinders and exhaust to exit the …
Since the exhaust valve is smaller and lighter than the intake valve, the stresses at the top between the keepers and keeper grooves is not as high as with the intake valve. Thus, they often succumb to a different, less exciting demise. A combination of poor valve quality and imprecise grinding causes the exhaust valve to allow superheated ...

Both the electrically operated SEG and pneumatically operated WSG Exhaust Valve Grinding Machines are approved and certified by MAN Diesel & Turbo A/S.
Thanks for the response. There was a lot of lapping done on the exhaust valves to get the pits out. The gray ring that lapping makes was probably 3 or 4 times as wide on the exhaust valve seats as it was on the intake valve seats. I'm probably going to take the head to a machine shop.

A valve that "talks back" or pops out the intake or exhaust manifold is obviously not sealing. The causes could include a burned valve, trash or carbon buildup on the seat, worn valveguides, worn ...
A wide seat also tends to trap deposits that can hold the valve off its seat. This too, can reduce heat transfer as well as compression. As a rule of thumb, the ideal seat width for intake valves is usually around 1/16˝. For exhaust valves, it's 3/32˝ – or whatever the manufacturer specifies.

Valve lapping is a process that ensures a perfect fit for the intake and exhaust valves in the engine cylinders on their seats. Usually lapping is performed after performing an engine overhaul, or when the old valves are replaced with new ones. Lapped valves provide maximum tightness in the combustion chamber, ensuring engine normal operation ...
Precise concentric cutter/machining operation makes for near perfect valve sealing without the need for grinding or lapping pastes that can reduce thermal transfer contact area. These pastes can be detrimental to satellite coated valves common in Japanese engines.
