The head is irrelavant. Its the compression ratio/pistons that are the problem !

Most turbo cars run 8:1 or less but N/A cars run over 9:1 some 11:1 depending
on how they are tuned.

YB heads are best suited for N/A when they have been skimmed too many times
and are below the head maximum deck height.
However, if the pistons are modified to suit the desired turbo compression ratio required
then this can be overcome to a certain extent.
