Check your vacuum lines for rips or tears. A hidden vacuum hole could be the culprit, as you said it was chugging during slowdown and shutting down at idle. Also, check the EGR tube for clogs.

All the lines seem good. I did a compression test on it and i have no compression on cyls. 3,5,6. Sooo Im thinking its toast. Getting everything ready to start pulling it out. If the timing chains break, do the valves hit the pistons on this motor? Ive never been inside anything other then a pushrod v8. Thanks for any info.

I got the motor torn down enough to see that the guide for the right cam is gone, also broke a rocker off. Hopefully I can get a set of reman heads and change them out and it'll all be good.
