What are you trying to measure? Height, width, length, combustion chamber volume ect..
Give us a clue and we may be able to help

The usual bit to measure is the rocker gasket face to head gasket face to see if it has been skimmed to death.
Cosworth engines like low compression for extra boost.

LOL yeah that info would help. Trying to see if the head i have is still ok (has enough meat on it). Looks like its beed skimmed and its going to need another. Ill get the digital caliper on it.

What would you cossy experts say the min depth is? Obviouslly the last thing i want is the valves hitting the pistons (i know its not uncommon for them to just touch). Should i go for the skim and buy some pocketed pistons or have mine pocketed?
