I pulled the intake and the fuel pump. I'll check the lifters tomorrow. All the rocker arms seem to be the same. Still could be a valve I guess. Motor stops when #5 and #8 piston are at the top. Noticed loose debris in #5 spark plug hole. Looked in the fuel pump hole at the timing chain looked ok. Most likely going to pull the heads. Like Pontirag and chubiw1 suggested.
