You won't be able to remove the head bolts with the engine still in. So no washer change can be done.
Why not ? Isnt it a 33 with an 8v engine ?
If its a 16v engine, then no he wont be able to do it. but an 8v ? Easy
Not that they have bottomed out, but that they run out of thread.
Just normal washers mate, something thin and solid.
Those bolts already have shim washers on them, thickness of a thin filler.
If you got spares of those, another couple will do the trick
From experience, if its a freshly closed engine, then there is no actual need to change the gasket. Yes its pressed and all, but its pressed on the same block by the same head with the same profile surface. If you were to skim the heads or change the heads, or if the gasket is pressed unevenly or its cracked or worn, then yes you should change it.
Just trying to save you some money and a lot of work mate
