CORTECO 20032CS

Identical to the stock mopar gasket I'm seeing and 5 dollar close out on rockauto. Another really close one is ROL. Corteco literally looks like named Mopar

Re: Head Gasket went, looking for advice

Pope is correct, MP gasket with copper spray and if you clean down both mating surfaces extremely well you should never have a H/G issue again.

This is the only combo we use and has worked well at almost 40psi boost and 600WHP in the Charger and H/G jobs we've done 15 years ago on lesser street TD's are still going strong today.

Copper spray both sides of the gasket, usually 2-3 light coats so it goes on even until hiding (all copper color)

The copper will help fill imperfections in the deck surface as well as the head, but it's the deck surface that usually needs it the most.

Make sure that your sockets & wrenches are 6 Point as the 12 point ones can round off the bolt heads & nuts.

Penetrant oil! Soak any rusty fasteners with this overnight and tap on them before loosening them. Be patient and apply more if needed. You DON'T want any broken bolts or studs to deal with. Not fun at all!

Torque wrench. You get what you pay for. Avoid those cheap ones from Harb Frt!

Some baggies & a sharpie to label & keep the fasteners in. It'll make it easier when you reassemble.

I'm sure our Resident Pros will add to the list...

Good luck & happy wrenching!

The Pope BTW if you go to the 11mm bolt, you need 2 sets of washers. Not the single set. The MP set cones with extra washers. As the 11mm set is for the taller 782 head. The other option is cross reference the 10mm bolts. If a more popular engine uses a cross reference you can use 10mm studs possibly. But a hunt lol

Re: Head Gasket went, looking for advice

Well, according to Pope we are comparing apples to oranges since the heads are not the same between your 84 and my 90.

I have used both Fel-Pro Permatorque and a Mopar Performance HG.

The OE lasted 90,000 miles before it went, it was replaced with a Fel-Pro and we did a "slip and slide" because I needed the car back on the road ASAP.
The Fel-Pro was working fine until I developed an Overboost issue (story for another day) and each time I checked/changed something I would take the car out and go WOT to see if the Overboost issue was gone, well one day the HG had enough and BOOM!!!
That gasket was replaced with a MP headgasket I got online before they were discontinued, I also installed ARP head studs when I installed that gasket.
The MP gasket lasted 6 years (about 21,000 miles) and developed a pin hole leak.
That gasket was replaced with a Fel-Pro which is still in the car.

The last HG was done in Sept 2016, 10,000 miles ago.
To be honest with you, I still use a bit of coolant (1 qt per month from the overflow bottle) with no visible leaks, is it from a HG sealing issue?

IMO and I am not an expert on the early cars with 10mm head bolts I would use the Mopar gasket if I could be sure there would not be any issues with it from sitting on a shelf for 20+ years.
If it were me, today at my age, being retired and not driving much I would just get another Fel-Pro and be done with it.

I am sure Pope will chime in again with more wisdom so we both can learn something. (Not being Sarcastic)

BTW...
When I was a Chrysler Tech (1995-2010) all Mopar short blocks came with McCord Gaskets so the assumption has to be that they were the vendor for Mopar gaskets.
My Grandfather sold McCord Gaskets in his parts store back in the 60's when I worked with him in the summer.
McCord was bought out by Federal-Mogul who also owns Fel-Pro so draw your own conclusions.

Re: Head Gasket went, looking for advice

Looks like a great find. I don't know the shape your original Laser is in but judging by the pics your new one looks great. I worked in a Chrysler / Plymouth dealership between '84 & '85 and can remember doing new car prep on Lasers. They were fun to test drive. I can't believe you found another one. I haven't seen one around for several years. Good luck with it.

Re: Head Gasket went, looking for advice

Okay, so I have got the car back from the mechanic and now have it sitting in my backyard. Gonna order the parts to do this but what head gasket do I go with? From reasearch on the forum I have done most people speak highly of the felpro gaskets but from what pope is saying up above the Mopar one is much better quality?

Also some exciting news, I was able to find in a town about 30 mins out from where I live a 1984 Chrysler Daytona, same gunmetal blue as mine, racing striped interior just like mine, 159K KM with only minor surface rust starting along the very edge of passenger door. Some small rockchips on the very front of hood but overall in much better condition then mine. Went and drove it yesterday and I really liked it. Talked to him about his head gasket as he stated he has owned lots of the older dodge turbos and is also a mechanic. He stated that he has always replaced the shitty factory gasket with the blue tinted felpro one, he said he would do this for me before I bought it so I made him an offer of $2800 which he accepted. I go to pick it up on sunday after he changes out the gasket on saturday.

But now I read this

So is there a better gasket I could order and get him to use instead.

Wish I had pictures still to show all of you the car but he took the ad down. I will be sure to post some once I get it. I still plan on doing mine here and will be sure to come back as I have questions, I am sure ill have lots.

Thanks all.

Re: Head Gasket went, looking for advice

To start the MLS doesn't work right on a factory 2.2. The surfaces need to be very smooth. The 2.2 looks matching by dragging the deck behind a pickup. So the grooves will cause leak. Next is cheap Felpro paper, 2k mileage with a turbo, same with the bolts. Next head cracking.

So the best option is lift the head, clean it and swap to the Mopar gasket. Spray with copper, use Mopar 10mm bolts to 70 ft lbs and no 1/4 turn. And get it going. The head is the older non 782 head, far less likely to be cracked. Do not take it to a shop and have them use their parts. They'll buy cheap Felpro crap and it'll need a gasket in 2k. tear it down, ring it, bearings, light hone, buff the decks. Add the MLS and it'll never blow a gasket again. But a kid in school...... Jack the head up and inch, screw driver clean and swap it. Bungy the timing gear, Jack the exhaust up to the floor. Piece of cake

All good advice.

Haynes Manuals are not recommended, for the same price...
You can get used FSM's (Factory Service Manuals) on eBay or get a subscription to https://www.alldatadiy.com/ for under $30.00 which has ALL of the info from the FSM's + some.
