What is the actual duration @ .050? advertized duration does not mean much.
What is the lobe separation?
I have run 12.0:1 compression w/side draft DCOEs w/a soild camshaft approx duration of 234 in 238 exhaust on a 112-114 lobe center. Cranking compression of 220 -230 PSI.
This was my daily driver on 91 or 92 octane.
Actual deck was positve of .002" -.004" range. .038 gasket thickness.
