just rebuilt runs bad

That cam the exhaust valve should be opening 78 deg BDC so something is wrong.
Your cam specs are on this page.

After thinking more about it, I'm just wondering are those cam specs in crank or cam degrees. If I understand correctly 78 cam degrees would equal 156 crank degrees. My 180 out was an eyeball reading on the crank which would make 156 in the margin of error for eyeballing I'd think.
