Ferrea 5000 Series Flat Face Valves
Ferrea valves are a good idea when you are building an engine. The 5000 Series valves have flat faces which would help slightly bump compression up a little in all motor applications, but can just as easily be used in forced induction applications as well.
We have seen multiple racers cut corners by leaving their valvetrain stock, and go to the track after spending thousands of dollars building a race engine with new pistons, rods, bearings, head gasket, cams, etc, miss a shift, over rev, and drop a valve into their newly built engine ruining everything. Usually when a valve fails and falls into the engine, its catastrophic and nothing can be saved.
In the big picture, the valves will be one of the least expensive pieces you could buy when building an engine, don't cut corners on the valvetrain, it could be the difference between losing everything or not.
