And did you clean the intake valves or clean anything before re install? And did you have to file anything on the fittings
My motor dropped a valve seat so my whole top end got redone. So the cooling mod was a no brainer to do while everything was easy to get to. And yes I did have to file down the small plate that came with the cooling mod


And does that plate on the fitting go into where the intake bolt supposed to go?
nope

It's not that bad. Just make sure you hit the freeze plug in the right spot to make it roll over.
I'm doing the suspension now and have looked at that plug. Looks like a pita. I was concerned about routing the bypass between the egr and fire wall,but if you didn't have any big problems I'm going to do it before the weather breaks up here.

IIRC you hit the plug at about the 9:00 position when standing by the drivers side fender. I eventually did a EGR delete, so the tube wasn't a issue.

I’m just about to clean the bore in the head, did you just lubricante the fitting and tap it in? And then install the plate ?
