What cam were you running with the 351's and the 383s? You have the 2.4 intake valves in the 383's? Looks like the 351 ovals have a 2.350 valve?

Standard cams. The 2.4 stainless intake valve is rough on the intake lobe it weighs a bunch. Recommend a titanium crn coated valve for this. New set up is a 55mm 937 keys lifters and titanium intake with sweet 16 brodix heads. 12.5 Cr and avgas. On hold for now.
