Fuel pressure is fine I had the brake booster line and purge solenoid lines to the throttle body crossed up but I have another issue I let it run for about half an hour and it started to get hot on me should I have burped the system?

Of course you have to get the air out of the system if it still has any. Why were the heads replaced in the first place? Was there a previous overheating problem?

The head gaskets were just the result of the overheating, not the original cause. You may not have found the original issue yet.

The only way you can be sure to get all the air out is by using a vacuum filler. You might want to consider putting a radiator in it.
