The 100 cylinder head is so prone to cracks that we will rarely try to fix
them any more. The problem is you will chase the cracks around the head for
ever.
The best answer is to just bight the bullet and install an aluminium head.
Yes i know they are $$$$$$ but they are far superior, flow better, lighter,
will not crack and run cooler.
I have probably 25 cast heads and would be lucky to find one the isnt
cracked. If i did once you rebuild that head correctly you got a lot wrapped
in a ancient design head.
Clean and Mag head, surface, repair and minor cracks, install new seats,
guides, valves, springs, grind seats, and next thing you know you have about
$800.00 to $900.00 in a head
that is just going to crack again.
Also remember that the head studs will stretch and the old copper style head
gaskets leak. So you should also install the upgraded studs and head gasket.
