just rebuilt runs bad

With a home made 360 degree tape going around the harmonic balance 360 degrees TDC to TDC. Set up a dial indicator on the rocker arm roller for each valve separately.

Intake:
At TDC compression stroke the intake is closed, stays closed a full revolution (360 crank degrees) then starts to open at TDC, full open 95 degrees, full closed 190 degrees, goes past TDC then begins open 360 degrees later at TDC, full open 95 full closed 195, goes past TDC then begins to open 360 degrees later at TDC, full open 95, closed 190, etc..

Exhaust:
At TDC compression stroke exhaust is closed, begins to open 155, full open 245, closed 135, starts to open 155, full open 245, closed 135 etc

I understand this is very shade tree. I'd give it an error of margin of 10 degrees, 5 if lucky. Is any of this info useful? When I get home I'll be able to analyze more but thought I'd through it out on the thread now.

Thanks.

Even 10 degrees out on your tape that cam is not in right.
The intake should start to open around 34 BTDC and shouldn't completely close for 280 degrees which would put it closing at 66 ABC.

If your saying the intake is starting to open at TDC and completely closed at 195 it not only is in wrong it only has 195 degrees of duration on the intake instead of 280.

I'm going by the specs of the cam you said went in it but even if it's a different cam no cam will start to open the intake valve at TDC, it will always start to open sooner.
