Da Nailhead adventures by whatever

The other day I was watching TV and there was this programme.

I started sh-tting bricks at 19 min!

I must have known about that before! I could fix that small hole (when it was small) pretty quick. Actually I thought about screwing a bolt it, but it was odd for me and I thought cast iron welding is easier.  However, this process is completely uncommon here! I even thought maybe I should dealer something here, hehe, though I don't see a great demand right now. The process is called cold metal stitching and you can do pretty much everything. The idea is to increase pressure in this area, so it'd seal - like a valve seat in the head. But metal stitching is not a structural reinforcement, it just creates some stress, so it won't hold a big load and can't be used on mounts or whatever.

Guess, I'm done with the heads!

Not absolutely ideally looking, but i'm pretty pleased!

Milled (ground) off 0.013 in.

These still need to be final cleaned and assembled.

The machine shop refused to grind flat the exhaust port sealing surface, cause they didn't have a base angle for it. (Duh!)

However, the exhaust sealing surface on the head looks fine, unlike the ones on the exhaust manifolds!

I've done 1st part of the intake manifold video, I think, it'd be better when coped with part 2.
