Will the stock Valves hold up?

Recommended Posts

Stock valves will do fine with hotcams. Or a BB.. But would have to consider better valves if stroking the motor..

+1 to the above, I've got hotcams with stock valves and springs. Only comes into play when changing to a more aggressive cam. (more aggressive than hotcam)

get your self some rhc valves.the stockers will hold up for a while but will soon fatigue and then you drop a valve and well you know what happens then

How many miles before swapping them out?

I just broke 10K on my stock parts and I've been told I should begin to become afraid. I'm in "the zone" so to speak. Good to hear good things about the Wiseco stuff though. Assuming decent quality control/consistency, can't argue with that mileage. Can the Wiseco stuff be run with OE springs and keeper parts?

You should be able to. I am using Wiseco valves, Kibblewhite springs:eek:, and stock keepers.

Still running OEM head except for Hotcams, 34,00klms and never had to reshim.

Once I get the RHC equipped head flowed it's going on.

I figure you can't F up a spring to bad.....or can you? Knock on wood!

how many times have you shimmed the valves and how many miles ?

I have re shimmed once, when i put in the HotCams. I switched speedos, and don't recall exactly how many miles i have on. I commute to work 16 miles each way.

I'm pretty well sure the danger lies exclusively in the super-fail of their valve design. I know that "a spring is a spring" is definitely not true, but KW has delivered several other good product lines (just not DRZ valves) so there's a decent chance they got it right.

I only switch speedos when I poop myself after doing a scary trick, I don't really go by mileage.:thumbsup:
