I ran a stock valve train for quite sometime with no problems. If you're going to get the KW valve springs and have it apart I would go ahead and replace with the KW valves as well, it's just another way to increase reliability!!

Stock EX valves are surprisingly tough. I'm still running the stock valves in mine, now 11 years old--bought the machine in August of 99'.

You'll be fine with the stockers.

To me it seems like running that cam plus stiffer springs would ruin the stock valves pretty quickly. They would be slamming shut a lot harder than the stock cam and springs.

if you do any thing get it p&p i have the stock set up in mine but i did have it p&p . if you feel its not good for you to run the stock set look at my sig. we are spraying nos with all the mods so you will be good.
