0.020" compressed, metal shim head gasket.
I far as I know.....nope!
How about copper? I know they can easily make one down to .022" thick.
Ask for Mordy. He already has the program ready.

The steel "Shim" gaskets are available NOS from various sources but only fit the 144/170. Steel shim gaskets for the 200/250 bore size are AFAIK - Unobtanium. Occasionally the "C9xx" .037 compressed thickness gaskets show up on e-buy or on this site for sale.

I have one! I tore an engine down this weekend, and it had standard pistons, bearings, original crank/cam, metal shim head gasket, no exhaust gasket, and the original exhaust clamps on the bolts. It was amazing! =)

It may very well be possible to re-use a steel shim gasket. With a good coat of copper-sealer, it could be attempted.
I haven't tried it yet, but thought about it and had a discussion with machinist about it right after I trashed one from an unmolested 250 - DOHHHH....
If anyone has a used one I'd be interested.

Just as a point of interest....the '82 200 I recently tore down had its original steel shim gasket intact. I mic'd it at .015" (!) which really surprised me. I saved it for possible future re-use since my setup is zero-decked (actually .006" out of the hole) and .009" quench would be pushing it even for me,lol.

I'd bet that rod stretch does occur but not to a great extent....less than .005" would be my guess. That is purely a guess too as I have no proof but my experiences with various engine builds to base my opinion on. I do know that the piston will grow several thousandths in height with the heat of full throttle operation-I've heated pistons and measured compression distance and observed .010-.015" growth in some cases.
My gut tells me that I could get away with .025" quench distance if bearing and skirt to wall clearances are correct. When I swap blocks in the Falcon in the next month or two (to make the T5 swap easier and to use the 10.5" clutch) I will have about .035" quench. Since I have no detonation now I want to push it a bit further to see what I can get away with.
Have you ever heard what the stretch amounts for alum rods at rpm might be? I've never seen a published number-just recommendations to increase quench clearance to accommodate them.

If I remember correctly someone here bought a few of them. he might part with one $$ 
it might of been falconfreak. i'm not sure if they were for a 144 or 200. Do a search and see what comes up.

I had 1, didn't look too bad, but I threw it out, thinking that all head gaskets can not be reused. my teacher ( I'm rebuilding the engine in my auto class ) kept calling it a Printo- Seal gasket. engine was rebuilt b4, the gasket had a red sealing bead, that looked like a factory sealing bead and not red sealer
IIRC,FTF had some copper head gaskets made by someone.Maybe he will chime in with some info.Leo

I have two....both from 1982 engines.
I have reused steel shim head gaskets on other engines but not a 170-200-250

i was helping my grandfather work on his 49 ford pick-up(it had blown a head gasket) he went into his garage and came out with a used copper head gasket and a spray can of high heat engine paint,he sprayed both sides of the gasket with a good coat and put it together and ita been running good ever since and that was 3 years ago,you might be able to do that with a steel one

Hey bluebird, how's your falcon coming along?
