Nothing to do with weight, but I noticed that on my new Kibbles, they have a more dished face on the valves vs stockers. What do the face of the Ferrahs look like? How much can the faces have an effect on compression, if any?

Done! WheatZ are you sure about the kibblewhite intake weight? That doesn't seem correct. If it is, there goes my theory about valve cupping due to lost spring control. I always thought (by looking at them which I know doesn't mean much) that the Kibbles were heavier.
What I really wish I had is a flow comparison which might be the first order of business when I get my flow bench up and running. The kibblewhite has a much different shape than the rest.

Il check my notes later to make sure i typed it right. If i dont respond back that means its right. I thought KB's would be alot heavier since there springs have almost twice the seat pressure of other valve springs going by KB's specs. I have never tested KB springs to check there pressure. |

I ordered the del west because they said I could use the factory seat. They were $400 shipped. Supposedly they have a special coating on them that's supposed to be really tough. I dunno tho, they look like bare uncoated titanium to me. I guess I'll find out.
