Is this the one that you're wanting to zing up to about 7000? If so, I'd feel a lot more comfortable with more spring pressure.

...either by changing springs or shortening the install height...maybe some -.050" locks, shims, etc.

...he may be ok. However, I love me some spring pressure. I've seen the effects of valve float and bounce at higher rpms and it's not good.
