A very good morning to all of you...could please help me work out the cr for a 1600 sub and 1400 head?.

Then i have a question...i seemed to struggle with an airlock in my coolong system, i figured out its because i never schemed the head when i redid the engine. Im now going to scheme the head and do a pressure test on it and make sure its all good. My question now do i really need to fit a new head gasket? there is a new head gasket on the car and the car didnt even drive for 5 kilos and do i really have to worry about my cr not being right? my motor still pretty stock please help?

Supply volumes of the head and the sub with the piston turned down 5mm in the block and head gasket compressed thickness then I'll give you the CR.

Not skimming the head will not cause an airlock.
You can reuse the gasket. To be sure spray it with spanjaard copper gasket maker.

BULLDUST !!!! Please don't ever take your car there for him to work on it. Anybody that can spew c r a p like that is a total moron.
It a a pressurized system and it will pee water out everywhere instead of sucking air in.
