I’ve read that and all of it is going smoothe, just can’t get the dipstick tune out, just need to get it out so I can get the header in. I didn’t need to remove it to get the manifold out, but I need to go get the flange of the header against the motor. It’s just stuck in there really good
I’ve had a couple people ask about that. I did mine around 4K miles so I was working with a new truck but I know a few people have broke the dipstick getting it out. It should just slip out. You may just have to be prepared for replacing it if it breaks.
