#310148 I've been googling and on HT and haven't found what I am looking for...
I'm looking into flat faced valves for a little bump in compression and maybe some power (Ferrea 5000 series) to be specific.
Has anyone used these valves? If so could someone chime in with any info they can offer.

Thanks!

#316805 I actually just ordered mine and they are at the machine shop as we speak. Ill get back to you with info when I start the car once the head is back on.

#316835 its a very small bump in compression... nothing to write home about. You probably wont feel the difference based of the valve choice alone.

#316888 For that little of a bump, you might as well just run a thinner head gasket, less work and provides nearly the same results for less money.
