NA Head Swap update

So i was waiting on making this post because i was hoping to see the chain guide. We had a catastrophic engine failure for the NA head swap on a friends car. It happened at focus fest in carlisle. Seems like the UHMW chain guide i made ate away and plugged up the oil ports, shown in pics. Its very frustrating for me because mine seemed to be good with around 200 to 300 miles. Thats all we really know at this time.
I had my engine apart anyway for re ringing the pistons and some other stuff i was having issues with. That forced me to rapidly come up with another idea. So the next solution was the chain guide V2. Made out of aluminum and uses the stock chain guide wear strip. This should solve the problem. As soon as my car has a streetable tune, then its on to testing it out.
