The welding went good but the bolt extraction didn't work. I put everything back together. I put some hi-temp RTV around the LR exhaust port (didn't want to but figured it might help some). Truck is at the exhaust shop to get headers connected to OE exhaust.

I guess I'm upgrading to 243 or 799 heads. From what I've read, it seems the way to go over my 317's. I have no plans on going boosted and only going with a small 210/218 cam.

 

mines been broke off flush for a few years now also.. when we installed the headers we put some copper rtv around each port, and never leaked.
