okay guys I need some valves for a All motor GSR... I will be using skunk2 pro2 cams. I am undecided between supertech or ferrea valves??? which is best.... Also what is the difference between ferrea 6000 and ferrea 5000 valves... 6000 seems a little more expensive.

Note: I am going to buy flat faced valve

ferrea valves the 5000 series would be fine for all motor car. From what i was told the 5000s are flat and the 6000 are dished valves. I was running supertech and 2 broke for no reason, i will never run them again.

From another perspective I have supertech and have ran them for thousands of miles, and my buddy's engine with skunk2 valves ate one of those and it has way less miles than mine. I guess luck has something to do with it also.

I have no experience with SuperTech but I've been running Ferrea flat faced valves (not sure on model #) on my setup for a long time now with no problems.

Nope only one set. They package the Intake and Exaust in seperate boxes, then the 3rd box has all my other stuff like Spring seats, keepers, and valve guides.

Ive used Ferrea, switched to Supertech this year, great stuff....and they make a lot of other valves and springs for other brands as well.
