I just took the plugs out and checked each one, no oil, no water, and all are the lite brown color.

Plus all were autolite so factory plugs? AutoLite 6 somethings

Nice clean heads. Good pictures too.

I'd imagine that wear is normal. The lines/grooves don't look very deep.

That looks exactly like my engine which I just changed both valve cover gaskets on. My engine has 136,000 miles. Even though I have the SOHC 4.6, I had those same little wear marks.

On my engine, they were no engraving, or scratches, shall it be put. Those are just typical wear marks from going over and over and over again a million-trillion times that engine has been turning haha. I felt each and every one with my finger and there are no groves, so i'm guessing it's just the normal wear of a healthy engine, all parts moves and it must eventually get a little wear. Your even looks as clean as mine!:D:D:D

Notice the difference in color of the heads/inside of cam covers between the L and R banks.
This is typical. IMHO it means the L bank runs hotter and needs the driver's head cooling mod.
But the heads look good.

I have never heard of that, how would one do it?

When ever my engine comes out, i'm definitely doing that.

I read on one of the post tho, that the freeze plug is located there only on 4V's DOHC.. So us with the 2V's SOHC, I don't know if we can do that.. Hopefully someone can come along and help with me information.

That's cool.....
I would change those springs if I were you, they are bad design and break (95 and 96 anyway). The new ones are honeycomb shaped. You will need new round keepers (hats) too. There are a few cases of this on the Lincoln forum, maybe others can add some info.

It looks pretty much identical to the 95 continental with 130K that I changed a spring on. Mine had a bit less of a line on the cam though. I was amazed at how well this and my SOHC 4.6L looked after so many miles..

Yeah I know of one guy who is running the rear-of-the-head mod in a PI SOHC.
The freeze plug that is unique to the 4V is at the top of the head, not the rear. The 4V is a "dry" manifold, meaning no coolant flows through it, while the 2V intake does flow coolant, hence why the coolant temp sensor is in the manifold for 2Vs VS. the crossover tube for the 4Vs. Because the heads are the same casting on both sides, there are coolant ports at the both the top front and the top rear, but the rear ports are capped off with a freeze plug, while at the front is where the crossover tube is installed(4V).
This mod is kind of overkill on a 2V application IMHO unless you are boosted and running serious power. The cooling problem with the left bank on 4V heads is well know, however. At first it was popular belief that it was overkill for stock 4V motors as well, but every single one I've ever seen apart looks exactly the same: the left bank is always way more brown, to me indicating that it runs hotter than the right bank.
I'm doing the "even-flo" style, meaning that I'm coming out the top of the head at the rear and routing it under the intake to the upper radiator hose. This works for me because I run C heads. On your B heads I think you have no choice but to use the rear freeze plug because the location of the IMRC actuators.
