naw,...that's goo sliding it's way to the centerIs the middle intake valve in the 2nd pic really damaged as it appears?

The engine has only ran a total of 5 minutes or less, I doubt your seeing carbon, more like the coating that comes from a water/gas/oil cocktail.it does look like a head gasket failure, unless you got your greasy fingerprints on the head gasket surface to fool me. but it strikes me odd that the number one cylinder would have such a good leak down reading, and compression reading, and have a blown head gasket.
the chamber however is loaded with carbon, way more than the others, which is why i suspect a bad valve guide seal.
Be quite and go drive your belly buttonWell it sounded cool while it lasted.
The blow down test should have given a hissing sound from the crankcase from any excessive leakage there. It should have shown up as bubbles in the radiator if there was a leak between the cylinder bore and the water jacket. Your leak down figures were excellent, so it seems that you have a good seal with the cylinder head and block. I am not at all familiar with the engine to even make a guess at the source of your problem. Like the rest of us, I'll keep watching this mystery to see who or what the villain is...
I called them, and the guy that answered this time sounded like he was a new guy. I told him that 6-8 months ago, I inquired, and sent them my only stock HG (from Australia). At that time, I already had the copper one from SCE,and was already going through my doubts about using it, and wanted to have a composite one made as a back up.Yank that 6 shooter and drop a LS in and be done!!!!!Lol
What about Lubbock gasket?
So wait... The compression check looked good but there is still water in the cylinders?
If that's right then is there a secret passage to water in this head to block combination?
What are these spits of water from, humidity was it? It seems like that would require a significant amount of moisture.
I looked at the thread before coming here, so I voted what the hell is thread about, but now I know better. I now pick "A".
As far as my commentary, all unscripted, off the cuff stuff. If I had put any thought into it, it would have been alot more like I write. (problem is,I would've had to edit that vid, and I was too excited to just to get the thing up. But after looking at it again,......the last section where I at the muffler is the telltale,...........that wasn't water condensation coming out the tailpipe,....it was water itself.
Now it's all coming together for me. When I first started that thing there was a puddle on the floor under the flange clamp from the down pipe. I passed that "warning sign" off as a cold, newly started engine and blamed that on water condensation as well. That engine was swimming in water.
The only reason I didn't hydrolock the thing (i believe) is that the pistons were sucking the water in when it was running. How it leaked 7% on the blow down and still was taking a bath is beyond me.
I've always been under the impression that o-rings are a must with a copper hg.Well that sucks with Lubbock, they have done many of my 6 cylinder tractor pulling projects.
Can see why it leaked! Copper with no o-ring does not work in my experience. Maybe in automotive with good head bolt pattern you can get away, but with poor bolt pattern 6's. It needs stainless ring with .040-.060 patrussion on the head side and a receiver groove in the block side.
