Where the easher sits
Different engine manufactures use different spec's for their valve angles. There is so much criteria used to determine that angle, it would fill a book. That's why they are called engineer's and we are called grease monkeys.

What is a three angle valve job?
The area where a valve closes in the combustion chamber of a four-stroke engine is called the valve seat. During a valve job, this seat is ground at a set angle, usually 45 degrees, for a good seal. In a three-angle valve job, additional angles are ground into each side of the seat angle to ease the transition and improve flow.
What is an angle valve?
The ports of the angle valve ( Inlet and outlet) are oriented at an angle 90 deg.
What is the recommended valve face angle for 1971 olsmobile 455?
The valve face should be ground to 46 degrees and the valve seat is 45 on all models except 4-4-2's. The 4-4-2 model is intake- 30 degrees and exhaust-45 deg. on the valve seat. The valve face is intake-30 deg. and exhaust- 46 degrees.
What does valve timing 0.006 mean on a camshaft spec card?
It is the "Advertised duration", used by the factory. It is the Valve timing from when the valve is .006inches off the valve seat to .006" off the valve seat.
Valve refacing and valve seat grinding and checking for leakage of valve?
yes
The part of the poppet valve that contacts the valve seat is called the?
The valve face
Why is the exhaust valve seat is made wider than the inlet valve seat?
Better heat distribution. The exhaust valve sees a lot more heat.
When do valves cool themselves down?
the valve transfers the heat to the valve seat (when the valve is closed)
How do you resurface a hot water valve seat in an older 3 valve tub shower assembly?
The optimum way is to remove (unscrew with a seat wrench) the seat and replace it. A seat cutter tool may be used to refinish the seat in place.
How do you stop an engine valve tap?
Valve taps often occur as a result of a misalignment in the fitting they are in, or a worn out valve seat. In many cases, a new valve spring and cam adjustment will fix the problem, but if it the result of a worn out valve seat, it will have to be machined.
What is the purpose of using the angle valve?
where the process require the fluide to be leave at right angleto the direction in which it enters at that time we use angle valve
How do you change a angle valve?
By shutting off the water supply prior to this valve of course
