1.94 intake and 1.50 exhaust
What size valves are in 1978 chevrolete1 ton motor home with a 350?
Probably 1.72 intake and 1.50 exhaust, but also could be 1.94 intake and 1.50 exhaust.
What are the valve size differences between a 305 and a 350 Chevy?
305s had 1.72" intakes with 1.50" exhaust valves. Depending on the 350, it could be the same, or have either 1.94" intake and 1.50" exhaust, or 2.02" intake with 1.60" exhaust.
What is the valve size in your set of heads?
Depends on the heads. The size is different for the exhaust valve and the intake valve, and different engines have different size valves. The valves are mechanical devices in the engine heads that open and close. The intake valve opens to let the air/gas mixture into the combustion chamber,. Both valves close the combustion chamber during the compression stroke, and the exhaust valve opens to let the burnt gas out during the exhaust stroke.
How many valves do you have?
Depends on engine size. Typically two valves per cylinder. One intake and one exhaust. Some higher performance applications can have four valves per cylinder.

Exhaust size of 1986 Chevy Celebrity?
Please clarify your question. Which engine are you asking about, the 2.5L 4 cylinder or the 2.8L V6. Then are you asking about the size of the exhaust pipe or the size of the exhaust valves or some other exhaust feature?
Is the exhaust valve smaller or bigger than the intake valve?
Intake valves are are almost always larger than exhaust valves . The exception may be in a low performance small engine where sometimes both the intake and exhaust valves are the same size.The intake phase of the 4 stroke cycle relies on engine vacuum produced during the piston down stroke to draw the fuel / air mixture into the cylinder.Vacuum (as opposed to pressure) is a relatively weak force; therefore a larger opening (larger intake valve size) must be provided in order that sufficient quantities of fuel and air enter the cylinder - for the engine to run.Removing the exhaust gasses is a much easier task - due to the pressure created by the upstroke of the piston.Because the pressure created by the piston is a much stronger force (than the vacuum the piston created during the intake stroke), the exhaust gasses can escape (they are actually pushed out) through a much smaller opening, past the exhaust valve.The intake valve is bigger.
Why do the intake valves expand and start making noise as soon as motor gets hot they are adjusted perfect cold oh the exhaust valves stay in adjustment no noise?
The valves are probably not changing size from the heat. It's more likely something is causing the cam to wear out, such as a lifters that are not revolving, the nuts are backing off, or your valve adjustment procedure is flawed.
What size valves does gm cylinder head casting number 83417369?
The GM cylinder head casting number 83417369 is typically associated with the LS-series engines, specifically the LS3. This head features 2.165-inch intake valves and 1.590-inch exhaust valves. These dimensions contribute to the head's performance capabilities, particularly in applications focused on increased airflow and power.
What does size and shape of the exhaust and intake ports affect?
It affects how the engine breathes. The better it breathes, the better the performance.
What is is the cc's and valve size for gm heads 10147898?
I have the same heads and from the info I found they 76cc heads with 1.72 intake valves
