My autodata manual says this:

Valve Clearances Hot

1159 (high perf.) and 1256 in. and ex. ... 0.008 in (0.20 mm)

hope this is correct.

:D

You also set them with the engine running. I always kept a set of gauges specifically for this job as they tend to get a bit bent.

The only problem with setting tappets, with engine running, is oil getting splattered everywhere from the rockers!!
Ages to clean it up afterwards!!

HA 1057 engine settings are different inlet and exhaust as well!

Is that not the same on the bigger engines?
