Keith, while you're into this, please give us your opinion on the Kaase SBF heads on a 393W or larger hydraulic roller cam warm/hot street motor, typical of what we see here. These things look hot. Cleveland style canted 2.10/1.60 valves, standard valvetrain, intake and exhaust bolts up (unlike Sportsman, or R heads that need a custom set of headers).
