I'd post this in the Engine Rebuilding forum, likely to have a lot of pro builders viewing that will know how to identify ;)

ETA -ignore... just seen that you have already....

That looks like the later ones w/ a headgasket

..... it maybe me, but they look a bit strange.

Here's old style cylinder from my car. It has dome

Yours look like someone machined recess... also recess surface does not look right, it should be mirror flat :confused: Part number is for newer style.

Unless it's photo that makes it look weird :rolleyes:

You're right...now I see it...I couldn't at first, but now I do...
Thans...not worth taking the risk on these...

Q

The box shows the correct number for later model 964's, however the cylinders and pistons seem to be the earlier cylinders/pistons....
