How to calculate ideal head gasket thickness required?

Does anybody know a way of calculating what thickness headgasket is required for a specific compression ratio?

It will vary depending on how much the head & block have been skimmed by as well as the bore size.


Also, does anybody know what would be a sensible compression ratio for a forged 5EFTE on a TD05 at approx 1.5 bar boost?

Thanks

a 1.2mm headgasket will be fine at that boost,

with wossner pistons you'll still have a cr of about 7.84:1, which is plenty low enough and shouldnt be to sluggish off boost
