The Vortec heads are a little bit lighter than the older heads and have a “kidney” or “heart” shaped combustion chamber that is more efficient than the double hump chamber.

Do aluminum heads make more power?

Aluminum heads will dissipate heat faster. This allows for higher Compression Ratios with less risk of Detonation. The cooler head also delivers a cooler air/fuel mixture to the combustion chamber. Cooler air is denser and can make more power.

They are perfect for a 350. Both the 327 and the 350 have a 4″ bore so they like the same heads. Old heads like that will have softer valve seats, so if you want them to last a long time, you should either replace the seats or run leaded gas in the engine.

Will 305 heads work on a 350?

305 heads on a 350 will raise your compression a good deal, maybe even too much for pump gas if you have flat tops or domed. I would go with 350 heads if I were you. If you have flat top pistons a set of 350 heads would be best.

How much boost can a stock 5.0 handle?

How much HP will turbo add?

Supercharger or turbocharger A turbocharger works with the exhaust system and can potentially give you gains of 70-150 horsepower.

Does a turbo decrease engine life?

Turbos Reduce the Lifespan of an Engine Again, it all comes down to design. However, a properly implemented turbo pushing enough PSI through a motor to produce respectable levels of power won’t strain a motor any more than idling in traffic will.

Does bigger turbo mean more power?

The greater the turbo boost pressure, the greater the engine power. Besides, boosting an engine using a turbocharger does not only help to increase the engine’s horsepower but also its torque.

How much HP can a tune add?

To give a ballpark figure – if you are on a stock car, you could probably gain 10-15 horsepower from a dyno tune. However, if you are running on performance parts like exhaust and turbo, then 50 horsepower gain is possible – even more depending on your engine and what performance parts you equip.
