I went to buy a set of ISKI double valve springs for my YB engine. They are not a supported engine / head by ISKI, so there is some majic being done by you guys to use ISKI parts (valves, retainers, lifters...) made for another engine.

Could you proud ISKI part owners please advise me the part numbers of all the ISKI bits you installed and whether any machining was required to fit them please.

Once we get the part numbers sorted I think ISKI will add the YB cosworth engine (head that is) to the supported engines list. I advised them that I would asking you fellas about this, I think they will be watching this post.


Thanks
