These are the valve guides that came out of the rear head, and the dimensions that they measure. Exhaust on the left, intake on the right. Compared to the Goodson website my guides must have come out of something completely different than a '79 FXEF 80" Shovel . . . ? Maybe a 1879 John Deere?
78 into 79 harley did a lot of mixing and matching on the engines coming out of the factory. Having a 80" lower end with 74 heads happened occasionally I've run across several over the years heads in particular could be any combo of stuff. Then you find the bikes guys have monkeyed with then it's anyone's guess till you get it opened.
If you ever watch shovels for sale over a long period of time 78's & 79's are the two most common resold years.

Damn!!!! I would never... ever... drive a Guide out with any carbon on it!!!!!!
At 200 degrees what was the "effort" involved with removal????
And those internal dimensions seem very "generous"
I hope something was fundamentally wrong with those guides, as now the seats are gonna sink quite a bit if a Proper Valve Seat job is Done!!!!!
I thought the Smart Money recommendation was a "Qualified Indy"

I'm saving up for new heads so I'm using these as a learning tool.
The heads were already f***ed up by a previous owner: Exhaust bolt holes were drilled and tapped oversized, O-ring intake has multiple large chips and gouges making it impossible to get a good seal (without lots of RTV, electrical tape and whatever).
The front head had some dings/gouges so bad on the mating surface someone tried to fix it by 'shaving' the head with a glass table top and course lapping compound (i'm told) and still used some sort of rtv to fill the gaps. I've been thru 3 head gaskets int the couple years i've had the bike before figuring this out.
It took about a dozen light/moderate whacks with ball peen to drive the guides out. I'm thinking they should NOT have come out that easy?

Very Subjective...
A few good whacks with a Heavy hammer are better than a Jiullion whacks with a lighter Hammer..and Who is doing said Whacking???
Very subjective... and a Touch [Done them before] is strongly suggested...
Next... how much is 1 tenth oversize and how much is 3????
At minimum get a learned/experienced someone over your shoulder.. This is IMO ... Not something one will Ever learn on the Internet!!!
OH...and In this case ... like Bottom ends... a dial caliper is Not sufficient... not even close enough... real Mics are a Necessity. again IMO

My friend that is supervising me and 'looking over my shoulder' is experienced at building his own race bikes for many years (retired now). Although most of his bikes are Japanese, he's had/has a couple Harleys in the mix (not race bikes) including his latest addition Panhead FLH. I believe it's a 1956. He's been generous enough to allow me the use of his calipers, bore gauges, micrometers, etc. etc. and he makes sure i am using said tools properly. I am doing my best to do things correctly as i don't want to make any expensive mistakes. I understand the risk.
That being said, and because my financial situation doesn't allow me the luxury of grabbing hundred dollar bills out of my change jar, I am doing as much work as possible. As much as i want new heads, that will be added to my wish list. I'm moving forward so that progress on the bike doesn't stall and turn into a dust collector in my garage.
Sparky what part of Washington you live in ? I'm asking as we're looking to buy a retirement place in Walla Walla in the next year or so. I'm sitting on a load of shovel stuff and tools I'll be thinning out.
