Need help on this one. We all know the importance of
getting this gasket right. Thanks.

In the first picture, there is no hole in the block
under the brass/copper hole.

In the next two pictures, two holes in the block are
covered by the gasket....there is no matching hole in the
gasket.

Paul, check out your gasket at the front brass hole.
I looks like there is no hole in your block either.

What do you think? Did your car run fine with this
gasket in prior to this pic?

Also, regarding orientation of the gasket: The tab
goes to the rear. It has the word "top" embossed on
that tab, so it seems I have it right.

2W,

I caught my error after looking at the pictures that I posted. Yes, my car ran fine from assembling just as shown. As a matter of fact, both Erik and the machinist couldn't believe how good the gasket looked after removal.

Definitely a first quality part.

Seems like I remember a tab on the gasket and it has to be to the back and readable. That made all the holes work out right.
Is that correct?

Correct, Norton. The side that faces up on the
gasket has the word "top" embossed into it. Clearly
that is the face-up side.

Once you determine the face-up side with the tab
at the rear of the engine, that would be the only
way the gasket can go on.

I must question why there are holes in the block that the gasket covers up. Seems a reasonable concern, no?

Also, in Paul's picture, the hole at the front of the
block that is rimmed in brass or copper looks as if it's
a hole in the gasket and maybe no hole in the block.
Hmmmmmm...........

It is fine they made it symmetrical so that you cant screw up and put it on the wrong way. The spare gasket I have for the Herald also has sealing rings for the oil passage on both sides.

It probably doesn't have a side marked top either.

They do this for a very good reason, the engine is symmetric, and there is no reason why the gasket won't fit either way. Of course if you only have one oil hole, and put it on backwards, you will ruin the rocker, head .... in a rather quick fashion. The extra crush ring must cost all of $0.01 and eliminates that risk.

Cool. What about these other holes that are getting
covered up? Still cool to install?

what about the hole in the block where there is no hole in the gasket? whats the hole in the block for and why no hole in the gasket? is there a hole in the head too at the same location, maybe post a pic of the gasket on the head before you put the head on

There ya go.

I'm bettin' the head has no passage where that "blocked" hole in the block is located.

Judging from this picture of the head, I would say that the good Doctor is correct again.

I counted 29 holes in the head including where the tape is and figuring one there. minus 14 for head studs leaves 14 for water and 1 for oil?( the round holes counted only) I tried to count the holes in the head gasket at the beginning of the post but not sure I can see them all, now this is starting to bug me and the bentley book doesnt show a good pic to count

As has been pointed out, there are no corresponding holes in the head. Boring the holes all the way through is much easier in regards to manufacturing than try to blind drill them. At least that is what I see in motorcycle manufacturing.
The design simply includes that aspect and deals with by use of the gasket and no holes in the head.
I am sure if you look at the old gasket you will see coolant staining or rust marking these area's.

No worries on the questions. Of course this is just my own opinion and experience.
Always looking to learn.

I've come full circle and believe that I will install
the gasket as is. Arguements were made that blocking
of these holes is most likely necessary.
