I completed my head and cam swap over the weekend, but now overheating, top radiator hose gets really tight like full of air, constantly air in cooling system even after I removed thermostat fan not working ( i did straight wit fan and still overheating), blower motor only blows defrost, and not much power. Head Gasket installed wrong causing overheating and air in radiator?
Need some assistance H/C swap

ok if your not sure how you installed the head gaskets, it's more than likely you installed them wrong. reason i say this is cause one of them go backwards of how it's labeled.
As long as the printed word ... FRONT ... was placed on the front of each side
of the block ... you are good to go.
With a lot of the head gaskets you find ......
It can appear as you are installing one of them upside down
Good Luck!

Try and taking out the coolant sensor behind the distibutor on the lower intake then fill until coolant starts to come out the hole put sealant on the sensor and put back in This method worked for me.
Mine were not labeled, I didn't put them on my brother did so I don't know for sure how they were installed.
Will this determine if gasket installed correctly or get all the air out? I have removed the thermo and pulled the top hose, filled up cooling until it started overflowing out of the thermo housing

I've had good luck countless times jacking the front driver's side up (making the radiator neck the highest point) and then running the car w/ the cap off, squeezing the upper radiator hose to get the bubbles out.
If there is nothing installed incorrectly, watch the overflow and fill it up to work the bubbles out over time.
Be cautious if you try it, moving belt, hot fluid etc.
The defrost thing is because there is no vacuum being supplied to the hvac. There is a thin, black tube that goes into the firewall around the heater hoses, follow it behind the intake and to the vacuum tee beside the brake booster. The line is likely broken or disconnected.
Good luck man!

Thanx, I was just reading this in another post of yours about burping the system. Also just to clarify, the water flows into the engine through the bottom house and back through the radiator through the top hose and the thrermostat installs pointing towards radiator. The only thing that really has me stumped is how hard the top hose gets when I put the cap on

Look at the front corners of the block, where the head and the block meet.
If you can see the headgasket sticking out, your brother installed it correctly. If you cannot see it, the headgasket was put on backwards.
If that does not help, ask your brother if the front or back coolant passages were blocked when he installed the headgaskets. The fronts should be blocked and the rear are supposed to be open.
About the thermostat, the spring faces into the intake manifold.
Check these things first, and then do the burping procedure as stated if they all check out.
So check headgasket orientation and thermostat position

I was thinking the same......
I do know that the tabs were at the front of the engine as we took pictures through out the build but none of just the headgasket on I only have after head but before intake and you can see the tabs at the front.

If I understand what you are saying .................
The tabs are at the front of the motor
If that is so ...............
Then just follow the wise advise given by those above

I just relooked at the pics and my head gaskets had tabs at both ends??
First, imagine it with the intake on.
The corners to look at are on the outside of the engines. Not on the inside where the intake sits.
Look on the outside front of the block, where the head meets. The headgasket should be protruding out.
Good Luck!

At work now but from the pics doesn't look like there is any gasket sticking out at the front bottom.
No tabs what so ever on the header side of the head, will try the burping this weekend.
