I was wondering the same thing. I seen Pro-x valves that are made by Wiseco for about $100. I know Ferrea SS valves are good but cost about $175 from Kenz. I have not found them online from anyone else. I would like to get a new set but don't wanna put up almost $200 lol.

I believe a few years ago there was a quality problem but it has been rectified, but since Kibblewhite basically did nothing for me when one of there valves basically destroyed and engine for me, I still refuse to buy their valves and I use Ferrea valves now............

I seen them last year and still kick myself. There were also some for about $100 shipped last year and I didn't jump on it:( I do agree about the look of the Ferrea's. Have a used set in my Barker head and they just look BA.:D Now I need some for my other money pit.

Stock valves have treated me good. Rather have the valve wear out than the head.....thats the reason why i dont go with stronger valves. Im running hc s2 and have had 0 problems

We mostly use KW valves for stock or +1 valves because they are cheaper and havent seen any problems with them, Ferrea's are very good quality but more expensive. Both valves are good.

So i need to have a valve job done ? When I replace my valves?
Can I just take out my stock valves and replace them with new stock valves
Or are u saying I need to have a valve job done when replacing valves period ?

Idealy you should have one done. I would also trust rocket factory's advice. You lap a valve by putting valve compound on the seat and the edge of the valve where it seals against head. You have a suction cup on a stick that you attact to the valve head. Turn the stick back and fourth. That way the valve and seat will match and seal correctly.

To do a real valve job they have a machine that grinds the valve and valve seat. Followed up by a little lap job.

I dont know what just a valve job costs. I have always just replaced the valves when I had the head ported. Most shops include a valve job as part of a port job. It didnt cost any more to change the valves out at that time, other than the cost of the valves.

I have kibble white black diamond or something in my willykiller head… Needless to say I have a lot riding on them to stay intact. So far so good. If I find a set of ferras on the cheap on ebay you bet your booty that I’m buying them…. A willykiller head is no joke…;)

If your valve seat are really bad like mine were you may want to rough lap them with an old valve before you start lapping away with a new valve. I did this by taking a stock valve (good condition), installing the compound and putting it in the head. Chuck the valve stem into a power drill and run it at a very LOW speed. This will allow you to put a little more force on the valve and not ruin a brad new valve. The reason I used a drill is because the little suction cup tool did not work good on the stock valves due to the letters on the face and I just couldn't get it to stick.

Obviously you will need to lap it again with the valve that is going to be in that valve position before you are done.

I just chucked a cut of bolt in the drill and put the suction cup on the cut off bolt.
