RE: Top end response

[Herb <zephyr9900@xxxxxxxxxxx>]

No, not necessarily floating them but more binding or just becoming unstable
  What kind of seat pressure do you have?  Are you using beehive or standard
springs, do they match the lift of your cam?  To tight of an adjustment on
your valve lash.  Unfortunately several things could be going wrong.  Are
all your components matching from same manufacture or mix & match? 
Unfortunately it is a tough subject to diagnose over the web.

Do you mean as in floating the valves? I've done that on other engines
before and this is not like that. It feels more like when a fuel pump
fails and only allows a small amount of fuel to flow. I had a truck that
had that issue and I could run it but it'd only do max of 25mph, period.
