Guessing this isn't good...
Posted by: Grandpacorvair ()

The first head removed from my 64 turbo core engine that I was hoping to rebuild..

This looks like significant damage from the dropped valve seat. Add to that the fact that even with 5 cylinders removed the crank is still 'stuck'. Plus two of the 5 piston rods are also 'stuck' and won't move AND we still can't remove the last cylinder/piston asm which is being very stubborn.

The other head looks OK, the 5 cylinders we have removed check out good. It's also going to need a head stud or more. It came missing one and we loosened one because the nut would not come loose. The threads look ok though...

Is this head beyond repair? Should I even think about having it repaired? What about the missing metal from around the seat... more potential problems?

If you're going to do it you may as well do it right...and you did.

Kerry....
If you are going to consider building a 1964, keep it all 1964, since there are a number of differences between the 62/63 turbo engine and the 1964 turbo engine. I am by far, not an expert on these engines, but I do know that when you start mixing parts from different years, that the end result might not be nearly as good as you might expect. Just one mans opinion.

I have run 62-63 turbo heads on my 66 turbo. They will work fine. Just don't cut them down.

"Is this beyond repair?"

Depends on which is more mangled, the parts or your budget. Depending on what your plans are for using the car, might or might not be easier or cheaper to find a running engine.

I'm assuming you would have to bore the early heads for use on a late.

That looks like the typical dropped seat I saw many times back in the 80s. They were on 80, 95, 110, 140 and turbo engines... I had a local shop that would eventually get around to welding the holes up and install new seats.

Better to start with another head, but a welder can fix it if he has the talent to..
