The recent text update on page 181 of the ANDRA Rulebook pertaining to Pro Stock engine regulations has been withdrawn.
The withdrawal of this is a result of discussions with the Australian Pro Stock Association and the ANDRA Board.
The following text, which was added to page 181, has now been deleted/withdrawn – “The OEM (or replacement standard head gasket) must locate on the dowels, clear all the head studs (or bolt holes), and align with the bore spacing.”
Therefore, the text reverts back to what it was before the update was published.
This change takes effect immediately, from 21st March 2024 and the rulebook file on the ANDRA website has been updated.
