TR4/4A TR4A head question

[tdskip]

Hi guys - can you please confirm that this is a standard late TR4A head set-up? Looks like it to me but would appreciate confirmation.

Thanks!

Hi,

1) Cylinder Head itself: I honestly don't know the differences in cylinder heads to say.

2) Exhaust Manifold: from what little I see from the picture, it looks correct. It should have two (not one) exit port.

3) Intake Manifold: it looks to be the correct one.

Now, to answer a question with a question. Your exhaust manifold appears to have been treated or refinished in some way. Any ideas what? Mine is still the stock one but very rusty. I would like to find a way to refinish it without having to remove it (call me lazy).

I have considered both
-Eastwood Manifold Dressing (rub on application)
-Eastwood Factory Gray Hi Temp Manifold Paint (paint on with poly brushes)

From your pictures, it looks the the Eastwood Manifold Dressing. The one downside to the dressing (according to Eastwood) is that it needs to be reapplied every few months. And my concern with Hi Temp paint is that if it does not perform as advertised, I will have a huge mess on my hands.

Hi Bob - I used the Eastwood manifold dressing. A bit messy to apply but it looks much better than what was there. I need to touch it up on this side still.

We'll see how it handles the heat.

It's tough to be certain from that photo, but I think that is an earlier head.
It should fit and work fine, but I don't see the flat above the #1 exhaust, and I think I can see (by tweaking the photo a bit) the marks where the intake ports were milled out after the head was cast.

Randall,

I think you meant the flat above the #1 intake according to TeriAnn's webpage on heads.

Tom,

Are the pushrod tubes aluminum or steel? I'm out of town on business and can't check but I'm pretty sure I recall mine being aluminum on my 1966 TR4A.

Gee, uh, you mean the big hole is the intake and the little hole is the exhaust ?

D'oh!
