Grinding And Machining Finished Valve Seat Width. The seat width is important because, about 70% of heat transferred from a valve; goes out the seat contact area. The old rule of thumb used to be, to try to maintain a seat width of about .070″. Today's engines, have valves that are so thin; it is impossible to locate a seat that wide on the ...
Cast iron seats are still used for light duty intake valve applications but should never be used on the exhaust side. The metal is just too soft to withstand the operating temperatures. For exhaust valves, a hard insert made of high chrome stainless steel, high nickel alloy or a heat resistant alloy must be used.
Intake and exhaust valves are available today in a staggering range of choices. In this article, we attempt to clarify and explain the differences, in terms of materials, their performance aspects, an overview of valve coatings and to provide a broad reference in terms of valve selection. STELLITE
Old valve before grinding . Now, on to the valve grinding. Depending on the extent of wear on your particular valves and valve seats, you may or may not need to use course grinding compound.

Step-2: Install Valves. The cylinder heads have been cleaned, Magna-Fluxed, had new valve guides installed, and the seats refaced. Now it's time to install the valves. In this case, the OE intake valves are within tolerance, so they'll be refaced and reused, while the exhaust valves will be replaced with aftermarket stainless-steel valves.

In case sodium filled valves are to be examined or large quantities are to be disposed of, the cavity is to be opened either by drilling holes in two different points without using coolant, or through splitting the valve open in the middle. Handling, machining and cutting open of sodium filled valves requires special care and great consideration.
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.

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.

If grinding, you typically need harder stones (ruby, nickel-chrome or stellite). If cutting, you need a good sharp carbide cutter and to slow it down a bit. For a 1.5″ diameter valve seat, a spindle speed of 400 rpm with a feedrate of 1.2″ per minute with a C2 carbide cutter should work well.
The hardened exhaust valve seat is driven into place. Once installed, the exhaust valve seat looks like this. It still has to be ground to mate properly with the valve head. Step-22: Intake Valve Seats. Close inspection of the intake-valve iron seat shows the result of a poor valve job. The intake valve wore its way deep into the iron seat.
