Re: 234 heads...

OS in Japan makes the cross flow dual overhead cam head for the L6. I didn't know it was 12K though! They also make 4 valve heads for 4-cyl engines like the L20b.

You can have custom work done to a head like puting in slightly larger valves and polishing the ports.

Re: OS 6-cyl engine

Ya, kinda like a Z32 engine

3.0 twin cam... that's 222hp and room to grow. But of course, its not a straight 6. :-)

You should start learning Japanese, and then take a trip to Japan and try to find this "OS" company. then bring some engine heads back and sell them for a profit!
