F, 2F (and 3F for giggles) Head Gasket Tech & Reference (1 Viewer)

I don't know about Europe or the ME, but the 1.5F heads in the US are either 60050, 60051, or 60052: Each was used for about 3-4 months of production over the course of the year the F1.5 was installed in the FJ40. The 60050 and 60051 look identical, externally, to me.

The last few months of production, the 60052 head has the 'step-down' head-to-manifold-studs because it seems the mfg was gearing up tooling for the 2F head. The 60052 head has 12mm stud holes, but still had to accommodate the 10mm Int/Exh manifold holes, so the step-down was a quick bridge.

These head numbers are not in the EPC or Microfiche, or at least I've never been able to find them listed anywhere... @65swb45 told me most of it. The rest of it became clear after acquiring a few different '74 heads. Also, be aware, the 1.5F head uses Head Bolts specific to that engine only.

The number you talk about is the one in the casting of the head?

From the EPC the partnumbers for the USA F.5 head are 11101-60091 and 11101-60092.

My engine was built in 10/73 (31008), so an early F.5, and the head has 60034 as casting number while EPC gives 11101-60075 and 11101-60077 for Europe.

I would be curious to see what kind of casting numbers the 2F heads got but either the EPC is f***ed-up or this casting number is not related to the partnumber.

The head bolts yes I discovered that when I was looking for replacements after opening my engine. Thankfully my old ones were still usable because those bolts are almost impossible to find.
As for some other particularities of the F.5 I'm still wondering why Toyota decided to change this and then went back to the original size 1 year later...

I recently found a 60051 head for my 74 F1.5. It has 10mm stud holes and I need the 'step-up' manifold studs for my manifolds which are 12mm. The only place that I can find them is $pector.
 
I recently found the correct 60051 head for my 74 F1.5. The manifold stud holes are 10mm and the manifold takes 12mm. I need the 'step-up' studs. So far the only place I can find them is $pector.

Yes, the part is NLA from Toyota. SOR has them reproduced. Only place you'll be able to find them. Bel-metric has some that look like they'll work, but I've never tried them.

This is getting off-topic from the OPs intent. Prolly best in a new thread...
 
I have a Siamese F motor I am rebuilding is there a head gasket kit with all seals?
 
I have a question. When did the F135 end and the F145 start? I thought it was 9/67 when the changes for 68 started. Lately seeing the wide intake manifold listed as 67-69. Thought those were only 68-69 models?
 
Digging into headgaskets for @02 champ

@cruiseroutfit did you ever find a -60030/-60031? I seem to have potentially found one on YAJ, however the validity is up for debate.

Yes, we've had/sold them. I need to see if we have any at the shop I can photo.
