It is exactly what it says. The number of valves the engine has per cylinder. If you have 16 valves on an 8 cylinder engine, you have 2 valves per cylinder.
1.94 intake and 1.50 exhaust
This casting number was used for the Dodge 318 and 440 engines. The casting # very often has nothing to do with valve size (Especially with Mopar) Dodge very often had a truck load of castings show up and be machined and installed on engines intended for very different uses.
The combustion chamber size of the heads with the casting number 376450 is 60cc. It is possible to install larger valves.
Valves control the in-flow and out-flow of fuel, air and exhaust fumes in a combustion engine (known as intake valves and exhaust valves). A 4-cylinder engine with 16 valves will have 4 valves per cylinder, with two intake and two exhaust valves per cylinder. With experience it is easy to tell the sounds of the valves apart because each engine sounds different with different valves. Generally the less number of valves means a deeper/throatier sound from the cars and vice-versa
Depends....a 2 valve per cylinder V8 would have 16 valves. A 4 valve per cylinder 4 banger would have 16 valves. There are also 3 valve per cylinder V8s...which would be 24. The number of valves does not necessarily determine what engine it is.
There 194 heads 1970 to 1980 heavy cast iron heads
Check the Piston Ring.
Valves per cylinder makes one's engine more powerful or less powerful. A engine that has 2 valves per cylinder is better that a engine that has only one.
16 valves
On a standard V12 it has 24 valves however some newer engines have 3 or 4 valves per cylinder making the number 36 or 48.
3 valves per cylinder ( according to the owners manual )
