Interesting afternoon of measuring and working on the heads.
Some stuff of interest for v6 owners.
1.6 16v inlet valves fit the v6 heads, and 1.6 16v exhaust valves don't.
the guides are the same as 1.6 16v ones.
Which means you can get wasted stem valves, and bronze guides very easily.
I attacked one of the heads, and removed the EGR shite from the exhaust ports, and ported one set of inlet and exhaust ports. The heads look excellent for power, very similar to the xe. Valves are 1mm smaller though.
I was going to post pictures, but the camera's out of batteries.
