No heat after head gasket change

I have a 2000 4.0 and i just changed the head gasket now there's no heat and a viberation at idle but only until i put in gear and drive it, after that it goes away when its back in park or nutural. Its got me pretty stumped so any help will be appreciated, thanks.

Yep, bleed the air out as far as the heat goes. The vibration however; only a few suggestions. Exhaust leak can cause a vibration but will still have power. If antifreeze got into a cylinder during the job it may have fouled a plug when you started it. This would cause major vibration that would lessen as RPM's go up. Serpentine belt centered on all pulleys? Good luck.

I use the stock Champions. They have worked great for me but I don't know anything about the E3's.

I believe I read somewhere that those E3's burn way to hot for either the 4.0 and 5.2. I may be wrong on that. But the stock plugs always worked great in these rigs.

burp the air out of the cooling system and find out where the exhaust is touching the chassis or body, crossmember ect
