Yeah it’s ran very similarly to that, also that’s how I had a 383 ran & slant 6 as well. Red flags? Also where do you think the combustion gas could be coming from?

Blown head gasket or cracked head would be the most common source of combustion gas in the coolant. A cracked or pitted cylinder wall would likely drive oil into the coolant too so if the coolant is clean, not a likely source.

I didn't think a domed piston worked at all with a closed chamber head.

I think you'd be better off to find a piston with a CH that puts it as close to zero deck as possible and machine the block to square and zero it. .039 head gasket would set your quench perfectly.

Sounds like you're keeping the stock rods so you might even find a flatop hypereutectic cast piston that would accomplish that economically.

Here’s the chugging upper radiator hose and a possible valve train tick/knock.

I’m going to start a new thread about the coolant and engine noise issues since it’s kinda off topic, thanks for everyone’s input on the L2295 and Stealth Head question!
