Can someone tell me the standard thickness of the headgasket of the Cosworth engine?
I am looking for hours in the internet, but I don't find any concrete value.

Some peoples wrote they "think" it is 1,3mm... is that right?

Actually, I have a Victor Reinz gasket YB1261 but could not find how thick it is when installed...

Further, does somebody know the standard height of the block and how much the piston may proud out of the block?

I need this in order to know how much the block and head has been skimmed before...

Thanx alot!

Cheers
