Headwork
It's a bit late to report, but last sunday, the overhauled cylinder head as created by Joost went back on the white Cooper. In the end, valve seats went in for all four inlet valves, because the other valves were not properly cut either (was just not as apparent as with the one valve). Joost also performed some magic on the flowing of the head, and reckons the head should already make a good difference.
