How can you tell if you have flat cam lobes?, Strange lash issue Options

[tornik550]

I am paranoid of developing flat can lobes on my recent engine rebuild. I am paranoid cause I have heard so much crap about the cam that I used- scat c45. I am asking this more for curiosity sake. I had a strange issue but I am certain it's unrelated. I set my valves on cyl 1 to 0 lash (chromoly pushrods). I did that at tdc for that cyl. Te intake and exhaust valves. Seem to lift normally. The issue is that at a different point in the cycle (other than tdc or full lift) the valves are very loose. The valves go back to zero lash at TDC. The compression is actually about 5 points better on that cylander. I think it's possible that the rocker shaft bolts may have loosened a bit, however I've already removed them. It doesn't sound like a flat lobe to me.

Clearly I do not have a great understanding of this stuff so please help me out. I out and made sure that I adjusted the valves at TDC. I only did this with cylinder 1- just for experimenting. I verified that I as at TDC for cyl 1 by the mark on the fan, groove on the flywheel palpable in the window on the top of the transmission and the distributor was pointing to cylinder 1. Here is what I found-

-At TDC for cylinder 1 both intake and exhaust valves were set to zero lash
-I then started to turn the engine slightly and feel the valves at differnet points in the cycle.
-During the intake stroke (with intake valve wide open) the exhaust valve has .004 lash
-During the exhaust stroke (with exhaust wide open) the intake valve has .004 lash
- back at TDC the intake and exhaust again have zero lash.

Before my original post, I had significant lash on the intake and exhaust strokes. I think that my lash at TDC must have been incorrect. When I readjusted everything now it is greatly improved however are my results above normal?
