Ford Repair: 85 Bronco full size 302, crank shaft, trick flow

Question
I realize that my grandson's bronco is past the year that's posted onyour site, but any will be greatly appreicative.  He has rebuilt his 302 borad 30 over with Trick Flow Heads / cam/push rods i think everything installed is Trick Flow except the Crank Shaft. The motor turns over but seems to have no compression. He thinks that the vowels are stuck. These heads were puchased from someone that said they were rebuilt but some people will tell y08 anything.  Do you have any help please?rhp4v

Answer
if there is little or no compression on any cylinder, remove the front timing cover and recheck the timing chain marks.. google how to set my timing chain on your "" "". it can easily be set 180 degrees out. there are multiple google videos from you tube that walk y9ou right through it
