Replacing the HG was just a preventive thing I decided I'd do while I was taking stuff apart. Hadn't shown any signs of failure yet, but it sure did look nasty once I pulled the head off!

How long has it been on there?

Would ask the same...

That does look nasty..

Nice lookin' bores. Do they all look that nice?

SamGrant951

Yeah, bores look good!

alxdgr8

Absolutely no clue....as far as I know it could be the original.
Yeah, all the bores look great!

Darwantae951

Good to hear!

Now clean that block!

NAhh, definately not the original. The one that I replaced was installed in 1993 and ohh man It was falling appart internally. From the picture yours looks like it was going the same route. Your Cylinder walls look good. Good time to add a Lindsey steam vent Kit.

Looks like a good call on the change. Did you pull the exhaust studs?

alxdgr8

Yeah...and broke one
Was planning on replacing all the exhaust hardware.

What's the best way to get a broken stud out of the head? Heat + EZout/etc. possibly?

I always pull the head with the headers attached, much quicker. My original head gasket was looking like yours, the top layer was de-laminating. Mine had started to leak a small amount of boost pressure into the cooling system. I am sure yours was getting close to doing this.

I am assuming you are getting new seals in the head so let the machine shop pull the stud. They are much better then most mechanics at doing this.

Good idea...I had been tossing the idea of having it gone through but hadn't decided yet. Just sent an email out to a local 944 shop to get a quote on it.
