That's tough to look at. Often when the the spring breaks it won't actually drop the valve. But when the valve does drop it it usually beats up the head and smashes the piston or in your case goes through the side. Has anyone sleeved a g3 hemi?
My engine is sleeved in hole number 2 so since the wall now has two diff metals in it I have to tune the motor to that cylinder as it's the hottest running hole in the engine.
That's good to know that they can be sleeved. I had a 324 Olds that was sleeved in all eight holes. It had .125 over pistons. Back then I thought that was the standard way it was done, make'm as big as possible.
