Looking at the heads there are a mix of bolts.  Some grade 7 with six tick marks, some with four tick marks (?), some grade 5 with three tick marks and all have an F in the center.  Four bolts just have FT in the center.

I have not removed them to measure the lengths yet.  But I thought it odd on one head the three center bolts have a grade 7 then a grade 5 then one with four tick marks.  The bottom five bolts under the exhaust header are a mix with six and four tick marks

Grade markings on the tops of the head bolts are as follows:
0 marks – Grade 1 or Grade 2
3 marks – Grade 5
4 marks – Grade 6
5 marks – Grade 7
6 marks – Grade 8

A large number of 1963-1964 292 engines pulled down for rebuilding have had the Grade 8 head bolts versus many of the earlier models having Grade 5 or Grade 6 bolts and a limited number of engines having head bolts with no marks at all.

No idea on the significance of ‘F’ or ‘FT’ on the bolts but I see Ford Y head bolts with and without those.   Could potentially just mean they are 'FoMoCo' bolts.  As a general rule, my own preference is Grade 8 for Y head bolts.  There would appear to be fewer head gasket issue with those versus the lower grade of bolts.

Thanks Ted.

I searched the web and no site I found with diagrams and listing showed 4 ticks.

I pressurized the engine and removed the plugs like you suggested but nothing spat out the holes.  Not even a drip.  But both tailpipes spat coolant out yesterday before
when I moved the car in.

My next move is to check the lengths like you told me.  I would not be that surprised if that is the case what with this mix of grades that looks like they just reached in a bin of spare bolts when they attached these.

Exhaust pipes will spit water out, especially in very cold weather, until the engine thoroughly heats up enough to dry out the moisture from condensation and the entire exhaust system gets hot enough to cook off the moisture in the mufflers from the condensation.  That is why it is suggested that a vehicle must drive at least 7 miles before the condensation is completely gone, or then engine run for 15-20 minutes at high idle speed.  New cars spit out water until they get completely hot the same way.  I see it all the time when leaving home early in the morning and following a neighbor or another vehicle that just pulls onto the highway.  Joe-JDC

I live in Florida.  It's 83 degrees.  This was neon green antifreeze that a dog with no nose could smell.  There was also antifreeze in the oil.

I didn't see mention of anti-freeze in the mix or color in your post.  That is another issue altogether.  Joe-JDC

That was a reply to Ted.  He and I had discussed that issue via email and, as usual, he has been a wealth of info and immense help.

Ugh, Oil and coolant mix in 4 head bolt holes.

I've seen plated bolts with several marks on top (don't recall how many) & marked "F" & was told they are "Fedalloy" bolts & are at least grade 8.. It was suggested that they are Aircraft quality..

Be careful where they go. From my understanding from 56 on there are 3 lengths and mine is a 56 heads and block.  I just took off a cylinder head that was installed in a rebuild before I purchased the car and found 3 in the wrong place. I decided to by a new ARP set since I had removed the other cylinder head for a ring/piston problem..  They are available for less than $100 and well worth it since you have a mismatched set.
