top of head full of carbon 1 inch deep what shoud i do

i rplaced my valve cover gasket today and found a very nasty head i just bought the jeep a month ago 2.5 with 122k i got most out with my finger i was told to leave it alone and put seafoam in it run a while and change oil then someone else told me to leave it alone and change the oil every 1k couple times and see if it helps and the valve cover was covered in it too but i cleaned it up real nice. What should i do it runs good but smokes a lil after idleing a while and when it first crank blue smoke thanks for any help

Carbon 1 inch deep? You need a beer keg full of seafoam.

If I were you I'd baby that motor and start saving for a rebuild. I really wouldn't worry about cleaning it out. If it's smoking the motor really needs a rebuild. I wouldn't seafoam it it'll speed up the death of the engine at this point. You'll have trouble with oil leaks and more smoke. Do a compression test. If it's high then seafoam it. If it's low start planning the new engine. The engine was mistreated in the past. It'll probably last a few more years if you just take it easy with the revs and just change the oil every 3 months or 3000 mi.

You should of taken a pic of this sludge. I also think if you break the sludge up it might shorten the life of the motor. I know this is true for automatic transmissions. If it were me I would run a quart of Mystery Marvel for a week or so then change the oil and run another quart of MM for 3k miles. It's a roll of the dice but I wouldn't want all that crap in my motor.

The build up of sludgy stuff on top of the head is sometimes due to lots of running without coming up to temperature, lack of oil changes, and stuff like that. It may also be contributing to the smoking by keeping oil flooding in the top.

Even more than changing your oil, CHANGE YOUR FILTER FREQUENTLY. Once that stuff starts breaking up (especially if you use an agent like Seafoam) there will be lots moving down into the pan

Probably won't be a bad idea to drop the pan and clean it out at the same time. I would carefully try to remove what is there in the head paying close attention to the oil drain channels. If you have a wet/dry vac that you don't mind getting dirty you can use that to suck up as much free stuff as possible.
