stock valves ober k.w. valves?

Is it worth the money and effort to change to k.w. valves. Should i just stick with two year old stock valves?

Well if you already have them then I would install them. K W had some bad ones a few years ago just hope there not from that batch.

Willys pictures of his blown motor will make you cringe. All becdause of a bad valve, that is why I said Ferrea but I haven't heard much about KW valves lately on here with them breaking. Hope they got it figured out.
