after replacing more than my fair share of head gaskets over the last 10yrs and cracking a 200 block i am now convinced the best method is as follows.
1 deck the block so it is perfectly flat with a good surface finish.
2 lightly skim the head again perfectly flat with a good surface finish.
3 counterbore the 10 bolt holes in the block to a depth of around 10mm.
4 cut a radius on the edge of the bolt holes do not leave sharp edges.
5 use a multi layer steel gasket.
6 standard head bolts correctly torqued ensuring the bolt holes are spotlessly clean before fitting.
i dont believe the 6 long stud method is the best due to unequal clamping forces which you are bound to get using 2 different types of fastener. i know several people who have had gasket failure on either no1 or no4 using this method. but at the end of the day everyone has thier own ideas on how to do things and its what works for you.
