Hello,
I had leaking pushrod tube seals and dropped the engine to make the job easier. I decided to pull the heads to check condition. I’ve done quite a bit of reading about whether or not gaskets should be used between the cylinder and case and between the cylinder and head. Some posters point to a service bulletin stating not to use gaskets. I have metal spacers/gaskets between the heads and cylinders. I think this engine has been rebuilt once before I got it. It runs well but it’s not as quick as another 914 2.0 I had years ago. Maybe the other car had higher compression and no gasket? I’m wondering if this metal gasket should be there. I haven’t checked for a gasket between the cylinder and case. My 356 has a thin copper gasket between the cylinder and case. Can anyone shed some light in this? Thanks in advance, Jack |

You will need to make sure you have adequate deck ht. No less than 1mm
The headgaskets are ~.8mm thick and do count as deck ht. If you don't use the headgaskets you may need to put a shim at the base of the jugs to achieve the proper deck ht. |
