That would be awesome if you get the chance to measure yours up! I was wondering the same thing if the ramp started sooner affecting the measurement I was taking. I’m going to be running some Crane 64-150 roller rockers on it. Would this cam need any special work done to the heads? The heads that came off the engine were 906s with bigger valves…however this engine was tossed into a field and had moss growing in the intake ports so the valve seats are trashed, trying to salvage whatever I can from this engine and get my other 440 running again. Thanks for everything!!
