Hope someone can help me here. I have a 1961 F-100 that has a 4.3 inline 6. We took the head to the machine shop for some work and I had my son take the guide dowels out of the head before we took it. Well he can't remember where they are and I need to find some. I have looked all over the web and can't seem to find them. I even contacted Summits tech support and they were of no help. Can any of you all tell me a good source to get them or a size/or part number? Any help is greatly appreciated!
Yes they are the same across all of those others as well. Just looked them up and it is the same exact part number for 260, 289, 302 and 351W or C.
Just as an FYI they are not even close to the same size in the 4.3. I ordered the ones off ebay from that link with the same part # C2OZ-6A008-A and they are much larger than the inline 6. Lesson learned I guess. If anyone need a set I have no use for them I will take as much of my $30 back as I can get. Also if anyone has the correct part number that would be awesome as well!
Feel free to buy the master parts catalog yourself and see. If that's wrong then not much I can do about this one. You can see I gave you the part number that Ford calls out. As always, it is best to confirm any information.
TA455HO what does the AR mean in that section vs 1 in the others? I see thats what it says but I measured the dowels at .685 and the holes in the block & head measure .528. I am on the search for something now that will fit even if I have to do some trimming. I fear without the dowels the head could walk and end in a blown head gasket. No need to do this but once. Do you know of a good supplier of these that will allow me to filter them by dimensions? That would make my search much easier. A lot of the sites don't even give you dimensions.

AR simply means "As Required".
I've been able to use the Ford parts on my trucks so I haven't needed to go to aftermarket. Can't comment on that.

I'm going to chime in here (for the first time in several months) because there is no such thing as a 4.3L because Ford didn't use liter designations for engine sizes until 1980.
4.3L in cubic inches is the 262 I-6 that was not available for F100's in 1961/62. It was only available in B/F600's and C500/600's.
So the only way your truck could have a 262 is if the engine was swapped.
What is the 4th digit of the VIN? Be aware that the 223 (what your I-6 F100 should have) & 262 I-6's did not use head dowels after 1962.
Chad: See the 1964/72 truck catalog, page 26 of the General Information Section for the specs the OP is asking about.

That's actually sort of funny to me. It doesn't really go into conversions like 4.3 = 262 or 4.9 = 300 but I get what you are saying....I *think*. I was going to remind the fella that Ford didn't use Metric measurements for engine sizes back in the day but just figured he meant a 262. But, I can see what you mean - and that's why you should stick around here - keep peeps straight and on the narrow path.

It tells what the conversion from fractions to decimals is. OP said the dowel holes in the head measured .528.
This story is somewhat vague...how does the OP know the engine is a 262 (4.3L) when it was never installed in 1961/62 F100's? There's nothing marked on the engine that shows its displacement.
What happened to the missing dowels, why can't they find them? What size is the OP's location, larger then a football stadium?
Kid could have stuck them in a pants pocket, so by now they may be doing the shimmy-shake-shake in the washer or dryer.
Ah, I gotcha now - I'd done the 43 divided by 64 math and came up with .671875 which is fine for the dowel measurement he got but the holes at .528 I had to assume was a different engine. All bets are off then.
