Engine pern, possibly NSFW

930 cylinder heads' exhaust ports CNC machined by Bill at Xtreme.
Can still barely see the tool paths through the ceramic thermal barrier coating.
Another great feature is that every exhaust stud is machined out and a time-sert installed -- way stronger, no more failing threads.





These heads breathe through...





Force-fed by...





...and cooled off by...



And if you're asking yourself, "Am I seeing ARP stainless 12-point fasteners all over that engine?"
Yes. Yes you are.
Methodically replacing nearly every external fastener with ARP, including all 12x exhaust studs. Goodbye, corrosion or breaking.
