Commence the teardown. I'm going to lay this out so that hopefully people can see what worked and what didn't on a high hp mostly stock engine. I went through it with a fine tooth comb and improved what I could on a budget. The motor got hurt on July 18, it was back together August 1.
Well that's nice. Porcelain is harder than aluminum for sure.
Obviously got the head too. Might be a little hard to see but it failed the head gasket and you can see where it torched the head into a water passage in the upper part of the photo.
Probably not related but intake gasket was funky on that hole as well.
The valves were interesting. Evidence everywhere of major valve float. If you look, you can see the valve tips are mushroomed over and I had to file them to remove them from the heads. It also had smashed the valve job basically flat. Live and learn, the stock valve springs were not up to the task of 6400 rpm, haha.
Bearings all still looked decent. Reused them.
Stock cast crank still mint.
Now this is wild to me. That's an entire engine's worth of rings. 1mm 1mm 2mm. Hard to believe.
Bare block honed and ready for the jet washer and hand wash.
Instead of welding up the one head, I just used a spare I had laying around. Fresh surface on both.
Valve job done and in the jet wash. The existing valve job was so ugly from all that valve float.
