Topic: F1 '76 cylinder head

[fr33man]

Hey,

One of the bolts for the manifold is missing and I think I might jest try and find another cylinder head instead of trying to fix it with a helicoil or something..

I dont know much, and haven't found a head for a f model.. my question is, can I use from a k model as long as it's song?

Thanks in advance

Just helicoil it mate if the threads fcuked.
That's easy enough to do.

I know, but Its a Big hole.. previous owner drilled it up to approx 13 mm and put in a bolt with epoxy..

Well it is repairable if the head is good to go again.
You could either get the hole filled with weld and drill & retap the thread or machine up an insert with an external and internal thread and make a custom helicoil.

It all depends on if you want to let it know who the boss is. 
But seriously mate, I wouldn't can it because of one buggered exhaust thread.

True - it's not the biggest job to fix it but with lack of time and me wanting it back on the road again asap it could be an easy option to get a new one

That's fair enough mate.
You could repair it when time allows and either keep it for a spare or sell it to recover some of your outlay.
Good luck either way mate.

The one from the K7 is identical.

Have you checked just how big the hole is? I had some big @ss holes drilled in my head only to find out that a regular old 12mm helicoil was find AFTER the "drill" and tap.

The drill for the 12mm IIRC is 21/64 although a common 5/16" works just fine with proper tapping technique. I bet you are right around there. Red loctite if the threads are so-so depth for the helicoil? The red loctite for the insert I mean.

Could also always pull it off and have a welder draw a bead for 20$. Gotta try to center the hole then tho
