Eventhough I still have the stock cam, I do have hardened pushrods and PAC valve springs. I wonder if that's contributing at all?

Nonnie, post up your tune so I can look at your settings

Just curious, what TSP heads do you have again? What springs are on them as well? Beehive or duals?

P.S. regarding the TSP heads, I think my track times attest to their value, especially given all these KR issues I'm having. Add slicks and no KR and you've got an ECSB well into the 13s on stock converter and cam.

When did that happen? I thought you had 317's with dual springs?

the heads themselves are 317s, but the CNC program is the same as the LS6's. Running just beehives.

The ports on the 243s and 317s are identical. The combustion chambers are different.

The heads supposedly flow 313 cfm @ .600"
