The pistons in my car are made by Cosworth for the CVH, they are not YB pistons. They still needed machining to obtain the correct compression ratio for the spec we are going for.

I don't really have any pictures of the CVH36 and I don't know if they will machine one with a CPS sensor pick up. They use blank cams which don't have the pick up but have a circular lobe on the end which was used to drive a lift pump for the carb fed CVH's so it could be possible.... Try sending them all an e-mail, see what they come back with...

Here is one of our suppliers which has a large stock of performance Ford parts including a lot for the YB which you keep mentioning! Have a look round the site.
