Try European in Cal. It used to be called Euro-race. Check out the heavy breather article on my site under 924 power tricks. They are the company that produced that head. Note that the board says that there have been some reports of cracked heads due to this change. I was not able to confirm this in my investigations about 1.5 years ago. I called them and spoke with them on the modifications they produced for this article. He can do what ever you want. They have all the records on file and should be able to duplicate the performance seen. They also made a stroker kit... so you might be able to get the pistons you want from them.

Good luck. Hey is that your 924? Glad you like it! Love mine.

well try to get them with skinny valve stems cuz when u upgrade to bigger valves u also get mroe restriction sicne stem is bigger, unless its a stronger material and they can afford to keep the stems slim, i think the bigger valves is a good idea though.

Vince I will try to get the pages working, but as I recall there are VW stock units that you can purchase that are larger yet stronger and lighter than the stock 924 units. Let me check it out and see if I can get the info to you. As I also recall there are VW connecting rods that are also good for weight savings.... less rotating mass.
It is all in the article, but it is not working for some stupid reason.

Check out the heavy breather article. It says that it used 44 intake and 37 exhaust.

Also the bolt on 2 article works in the are a that speaks about the valves. Page 2 I believe.

Just remember some have reported cracks, but I have never seen these reports.... just hear say.
