Gotta go with Bob on this one, especially looking at the lack of gasket imprint on the other chamber on the right.I pretty much recognized the gasket from the picture. Read the description.

There is a reason the cost twice as much.
It could have been worse. It could have been a $15.00 8180 PT2
Less than perfect decking, at that compression, with that gasket is certain failure. You get a machinist pushing the fly cutter on too much angle and it leaves a low area right down the center of the head and or block.
With that compression, and iron heads, you have to give the engine a fighting chance by having everything PERFECT.
Tune, machining, and materials. It didn't take much to blow that particular gasket out between the cylinders.
My suggestionsThe engine never went past 180 and was only at that for maybe 30 sec.
Not sure of the machining

Another pleasure boat. I feel like a heroin addict.
Time for Alum. Heads. Any suggestions?
Thanks for the help guys
Listen what Bob is pointing out.
I would give Barry 001 a call and ask for a little help sorting it out.
Make a appointment to bring it over.
Barry, has a machinist eye for detail, let him look it over.
Then he can tell you the good and the bad news.
The newbie Scott Foxwell is in the head business I would go with a proven product and use Steel comp :shhh:
Did you clean the quench pad on that one chamber, or did it come off the engine like that?
What's the other side look like? I saw one at a buddy shop had the coolant restricted on one side, about the time the temp gauge went 190 it was already loosing power. It torched the head as bad as that one and the block too. The other side looked just like a motor with less that 2 hrs.
In addition to this idea, I'll add not to use the same head fasteners. With those stocker gaskets the stocker bolts, (if used), never gave it a chance.... Even if you had/have ARP studs, replace them...DO NOT USE THE SAME HEAD GASKET!!!!
