The 8553PT are what you show in your picture.

Im curious how can you tell by the picture, is it the color or is there a shape?

I will be real interested to find out what thickness the head gasket is. Maybe it was the piston to valve clearance that caused the cam to fail.
Was the lobe that failed on # 7 or 8?...... them are the tallest pistons.......
I'm not as much interested in brand as in thickness of head gasket.
The eddys came in two flavors one ment for the higher compression eng and one ment for the low compression 340/360 eng.
So yes, them are the wrong heads, BUT the proper head gasket will fix the problem.
The 340 head had a small ring, the same size as the bore to let a pop up piston have plenty of clearance.

Ill measure the head gasket tomm, of course it wont be dead nuts cause even though they have been compressed Im sure there is some bounceback.

Ill either get better pictures of the bad lobe/lobes and or try and figure out what and where things went wrong.
Let me ask how am I gonna get a specific C.R if Ive got to put such a thick head gasket just to stop the valves from bouncing off the pistons? Am I gonna have much choice or control or is it gonna be what it is assuming I can get one thick enough.
Can I have a chamber cut into the head to allow for the tall pop-ups?

Maybe I need to get a shorter piston?
