Is the correct plug gap for the recommended Bosch W4CC plugs fitted in a '78-79 911SC 30th/in (.8mm)?

Migration info. Legacy thread was 5235
 
This has been discussed before, I have a feeling it may be W3CC. Ill check.

The gap is probably the same for both but I'd like to be sure . The Porsche spec . book doesn't cover these plugs .

ha ha!
yes well I changed the plugs and gapped them correctly , strangely enough I didn't get one reply on the correct gaps from anywebsite I posted the question on . Maybe it was too easy! Piece of cake changing the plugs since Nick Moss kindly backdated the heating for me .

how did you get on retrieving the plugs from the cylider head wrench says use a short length of garden hose to fit over the spark plug heads to get them only with COLDengine though eh...

It was easy just using the standard tool kit plug wrench, engine cold.

plug gaps for 3.2 carrera Bosche plug WR7 DC ARE 0.7 -0.8MM/0.028- 0.32IN - ACCORDING TO BENTLEY PUBLISHERS 1984-1989 Carrera MANUAL

I found that my 3.2 Carrera had a much smoother tickover with cleaned up distributer (internal terminals) and a cleaned rotor arm terminal.
