Waste of bloody time. Also fiddly to fit the aluminium spacer blocks to the curved head ports - more putty.
Had to bend the kickdown rod to clear the extractors, meaning that never worked right again. Took the car out down the length of Heathcote Rd and back - a distance of about 30 miles. Down on power and 57 mpg! So it was running hit-you-over-the-head lean + no heated inlet manifold. Rejetted the Zenith, but it never ran the way I liked.
Got a job in the city and left the Zephyr parked at my place and only drove it weekends. The extractors rotted after two years! (out of warranty, natch). Traded it on the XK with a proper cast exhaust manifold (which cracked years later, but was able to get it welded and fit it without taking the inlet manifold off as it was cast into the head, lol).
