All 348/409 water pumps on the market today , whether they are Edelbrock, imported aluminum or cast iron have a flow rate of 32 GPM @4000 RPM with a 7" crank pulley and a 7" water pump pulley. Which is best? Can't say, we carry them all.
We carried rubber valve cover gaskets made by Fel-Pro for many years until they discontinued them last year. Many guys preferred those over cork.
All the "cork" valve cover gaskets we can find at this time are not made of cork, but of some kind of synthetic.
If anyone can steer me towards rubber or real cork ones, let me know.
