Did you check the spring pressure after tear down . seat and open to see if at it's installed height( in head as used)it was within spec for that cam??
I.E. did it float the valve.

I haven't checked the spring pressure, they're still on the heads. I gave the spec sheet to the shop that set up the heads, and I didn't check them myself after he set them up.

They recommend use of Performer RPM cam, hyd roller & Performer RPMintake, those are all spec'd for 6500rpm operation, per Edelbrock. Don't know why they would include valves that wouldn't be good for the same RPM.
