Integral valve seats typically run hotter than inserts because they are often made from the same material as the cylinder head, which can lead to higher thermal conductivity and heat retention. Inserts, on the other hand, are usually made from materials designed to dissipate heat more effectively, allowing for better temperature management. Additionally, the design of inserts often allows for better coolant flow and heat transfer, contributing to lower operating temperatures compared to integral seats.

What are the type of valve seat?
Valve seats can be categorized into several types based on their design and application. Common types include integral seats, which are part of the valve body, and replaceable seats, which can be individually replaced when worn. Other categories include screwed-in seats for easy replacement and soft seats made from materials like elastomers for better sealing at lower pressures. Additionally, seats can be classified by the type of valve, such as gate, globe, or ball valves, each requiring specific seat designs for optimal performance.

How do you replace valve seats?
To replace valve seats, first, remove the cylinder head from the engine and clean the area around the valve seats. Use a valve seat cutter or grinding tool to remove the old seat and create a precise recess for the new one. Install the new valve seat, ensuring it's properly aligned and seated, then reassemble the cylinder head and reinstall it on the engine. Finally, check for any leaks and ensure proper valve operation.

because ur heads need inserts..2500 dollar job
Do chev 350ci engines need leaded fuel?
If it's a real old engine ( 1979 or older ) they do because the valve seats are soft not harden,and todays fuel will take the valve seats out of the heads. If you are going to use old heads with todays gas they will have to have hardened seats put in the heads.
Does the 1969 Cadillac.472 have hardened valve seats for unleaded gas?
The 1969 Cadillac 472 engine typically did not come with hardened valve seats designed for unleaded gasoline, as it was produced before the widespread availability of unleaded fuel. Most engines from that era were built to run on leaded gasoline, which provided lubrication for the valves and seats. However, some owners choose to upgrade their engines with hardened valve seats to enable the use of unleaded fuel without risking damage.
What lead additive do you use foe a 1973 v w karmann ghia?
