Dowels

Hi all,



I am currently in the process of changing the head gasket on my 2004 MGZR 1.4. The new gasket comes with a pair of steel dowels, however, the block already has steel dowels fitted and I am reluctant to try to change them if this can be avoided having read other posts on here where people have had difficulties in fitting them and in some cases have had to drill the block.



Is changing them essential or can I get away with leaving the original steel dowels in position?



Thanks



Andrew
