Copper beryllium has great heat transfer properties. I use it in molds all the time where I cannot get water in for cooling. The Copper beryllium will draw heat from the exhaust valves and keep them cooler. (Heat dissipation)

I recall reading, Potter uses material unknown to me for valve seats....reasoning includes avoiding Ethonal effects.....May be worth checking on.

I use them all the time.

Okay, so the great heat dissipation over the other steel seats is what makes the copper berylium seats flow/breath better???

Do the copper berylium seats really breath better to make more HP or---is it just that the CB seats have better durablility, etc. ??????

The CB seats sound great and the bennefits of the material alone seems like a great advantage for endurance and durability---but what I really want to know is do they actually flow/breath better (if at all) than any kind of steel seat that is normally used? I cannot imagine a CB seat making anymore power or flow vs any kind of steel seat---it is all how it is machined (I would think) or shaped in the valve job, but I could be wrong. Not trying to start an arguement...just curious. Can someone get me straightend out on this please.

Maybe this info can help. I do not believe that they flow any better, it is all about keeping the exhaust valves cool.

Worx for me !!!

We ran Del West titanium valves with the berlium seats. I can tell ya first hand titanium exh valves don't work a 9.0 to 9.5:1 compression ratio. Intakes were fine.
