Head gasket **PICS**

[Cable]

i usually line the cams up before taking the head off, but if it changes yh i just make sure i turn the engine 90 degrees before moving the cams.

I would listen to Wayne's advice.
He is usually pretty spot on.
What is the damage on that piston crown? it does look like the valves have hit it.
Always use new head bolts, not because they might snap, but more importantly once stretched they won't stay tight if you use factory settings.

its not a valve hitting it because it only had that mark on the one side of the piston, its just a manufacturing mark, i think they were cast and not forged .

The inlet valve doesn't have that shape, they are concave so they wont be able to mark the piston in that way.

Myself and others are only going on the pics, which are just pics, not the same as examining it in person.

I have arrowed a mark that is I am 99% not factory but looks like a valve has hit it in the past.

+2
I can't see any cast marks on the other crowns.
The indents are the shape of 2 valves.
