Okay as I am reading this: You replaced the timing chain and tested the engine. Then discovered that you had no pressure in that cylinder.
That is an interference engine and the blockage you feel is the valves hitting the pistons because it is now out of time.
Probably the best solution would be to remove the chain, remove the head and verify that there was/was not contact. Then proceed from there. Especially when you had no compression in that cylinder when you tested. It may have already bent a valve or two when the tension-er and guides were bad initially.
