If I take 2mm of a standard head and run with standard 10:1 CR pistons what compression ratio will I achieve?

get her to set the camera to manual and have a play

small depth of field ie 1.2 will give as small area of focus which is for good  detail

make sure u have enough focus to get the whole car sharp   ie F 22

it gets a bit tricky deciding whats worth seing in focus

but I'm sure u will get what I mean

 

focus on the caris  important let the rest fall off and look and  good

 

basic 22 or 32 everything sharp

1.2 .8 very small area sharp

cars need alot of focus unless u are shooting badges and name plates

you don't want the bonnet sharpe and the boot soft (UNLESS THATS YOUER STYLE)

  shallow depth of field for details

wide depth of fied for big wide important  shots

 

 

 

but what the fcuk do I know

 

I only do this stuff on adaily basis

Max you can take off is 1.4mm. After that you hit the oil jet. 1.4mm would give around 11.5 CR with standard pistons, more with the Wiseco and the thinnest head gasket. See Alanoo's thread:

Confusion....

Some saying it is possible to take 2mm off a SAAB head, which is obviously more than the 1.4mm recommended off a standard Z22SE head.

Anybody any experience with the matter?
