How does a vortec engine work?
The word 'vortec' is the name of the cylinder heads used in Vortec Model engines in the year 96'+ The engines that use the Vortec cylinder heads are the 4.3L Vortec, 5.0L Vortec, 5.7L Vortec, and 8.1L Vortec. They were only put on Gen I small blocks. If they are any other size Chevy engines and still retain the Vortec name then it's purely a marketing name, the same goes is it is later than a Gen I engine. For example the new 4.2L I6 from GM retains the name Vortec, but it does not actually use Vortec heads as these heads were only made for OHV engines, and the I6 is an OHC engine. The Vortec heads are based on the LT1 and LT4 head after they were discontinued along with their reverse flow cooling design. It is simply an effect made in the head similar to a vortex to better atomize the fuel and air intake charge when entering the combustion chamber, it is not a different type of motor.

What is the combustion chamber size of 305 heads?
The combustion chamber size of 305 heads, specifically referring to the small-block Chevy 305 V8 engine, typically measures around 58 to 64 cc (cubic centimeters). This size can vary slightly depending on the specific model and year of the cylinder head. These heads are commonly used in applications where lower compression ratios are desired.
What is the combustion chamber size of a Chevy 350 stock head?
The combustion chamber size of a Chevy 350 stock head typically ranges from 64cc to 76cc, depending on the specific cylinder head casting.
What size combustion chambers do Chevy L99 heads have?
Chevy L99 heads typically feature combustion chambers that are around 62cc in volume. These heads are designed for the L99 engine, which is a variant of the LS series engines used in various Chevrolet vehicles. The size of the combustion chamber plays a crucial role in determining the engine's compression ratio and overall performance characteristics.
How does combustion chamber size effect an engine?
if you make the combustion chamber smaller for example by shaving the heads when the sparkplugs ignites , the piston will get pushed down harder there for make your engine go faster .In short, reducing the combustion chamber size increases the combustion ratio which increasing the explosive force of the air fuel mixture when it burns. The negative side of this is fuel with a higher octane rating will have to be used to run the engine.
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.
Will Chevy 305 heads fit a Chevy 350?
You will need to have the heads for the 305 bored out to the same size as the 350. I disagree: you can use the 305 heads on the 350 block but you will increase compression as the 305 heads have a smaller combustion chamber. The critical dimension is valve clearance. If compression ratio is a critical consideration, different pistons may be available which will bring the combustion chamber back to size. the 305 is from the 3.671 inch bore family. The 350 is from the 4.00 inch bore family. All small block heads have the same bolt pattern.
