Topic: 67 GT350 Engine Gaskets

[Bossbill]

On the SAAC Forum a comment was made that 67 GT350s would have regular cork gaskets.
But then it was noted that "Since all GT350/500s had aluminum valve covers  , they would not have tabs."

Comments?

Is this the color of the thermostat gasket?

That is the color that I have seen when dissembling survivor S2MS intakes .

+1 and they look to be shaped correctly also

Not sure who made that comment or what thread it was on the other site. But IMHO it is not unusual to hear and see all kinds of comments and peoples "logic" on forums or at shows.  Recalled one story way back int he 80's were someone informed me that I didn't know anything since I didn't know that 65 Shelbys were delivered to the Shelby plant with 6 cylinder motors since they were "running short at the time"  and SA workers were swapping out engines and transmissions there. 

As we've discovered our "logic" today does not always reflect the choices made by, or logic of the workers, people concerned about cost as well as inventory or supply issues and engineers of the time period. But of course we have the benefit of being able to look backwards and in some cases "Monday morning quarter backing"

Today we also have the benefit of unrestored and period pictures that can be shared widely unlike the past, to help research and sometimes used to debunk statements

Here are some pictures from magazine articles printed in 66-67 showing 67 GT350's engines and the valve cover gasket tabs Believe picture #1 and #2 are the same car from different angles and possibly different articles. Top and bottom side tabs are difficult to find in magazine shots

Great pics to back up the black gasket.

Other than the carb base gasket this is all really well defined. I appreciate all of the help and I'm sure others do too. The list at the top contains the latest data.

I bought those thermostat gaskets so I may do the "donate to the site" and I'll give you one!

While searching for a head gasket with front extension and hole, I came across a possible reason for this design.
The Felpro 9333-PT-1 head gasket is the recommended head gasket by FRPP for early cars (In the M-6003-A50 kit). In the instructions is the attached note (see pic).

It appears this would be a quick and easy way for an inspector (and you!) to see that the head gasket is installed correctly. It's also a gasket that replicates the early style in this regard and all I have to do is modify it a bit.

I'll order a pair and see if I can modify it to be a bit squarer and see if it drills nicely.

I order a set of FelPro 9333 PT-1 head gaskets and I placed it on a 289 block along with a spare head (yeah, it's dirty).

Here is Jeff's  pic:


And attached is a pic of that gasket mocked up on an engine.

Just use a punch to make a hole and I think it works.

Did you happen to save the old gaskets to practice?  Seen guys punch them out and often that will smash the inner layer, turn the edges of the hole  inward pr if not supported well when punched will leave the bottom side (or top top if they didn't do them as they sit installed) deformed.  Wonder if drilling would produce a better end result - the reason to ask if you still had the old ones

Just a thought

Fel pro intake gaskets are of similar construction, it appears. Outside of the fire ring, that is.

I used a piece of soft aluminum under the gasket and used a 3/16 hammer punch and then a 7/32.
The aluminum was solidly clamped in a very solid vice.

I think 7/32?
