It's more important that all the cylinders give similar readings.

What values are you getting?

Ive not done it yet bud was going to be more a part of my pre winter service and thought this might just be worth doing to check all is okay bearing in mind i did the head gasket not long ago

Checking for residual pressure in the expansion tank when engine is stone cold is probably a much better test of whether HG repair is holding.

it all appears to be good and no pressure and clean oil and coolant its just since i did it its lost some acceleration it seems to hold back then accelerate and i did not have the issue before the head gasket change im even tempted to reset the tappets but I thought as they were hydraulic after the initial set they would be fine but its just not quite right somewhere.

I've no clue what the acceleration issue is, but no harm in measuring compressions. 

Its not stuttering or stalling or anything and fuel economy is great since head gasket change there just seems to be a delay like if you had a diesel and turbo lag.
