no he means stronger bolts.... the original bolts stretch with expansion of the castings when there hot, and may not fully return to the original length when cool = loose bolts.

a higher 'grade' bolt will take much more load (stretch) before perminantly stretching.

I have heard that ARP can provide bolts for this job.

and Nordlock washers get a thumbs up from me, recently got some of these from work and used them on a friends car when fitting a new manifold -> turbo gasket, perfect for the application :)

Are these any good mate or do i need thread all the way up the bolt?

length depends on manifold..
std ones are shorter than those on a jbs or ina/034 manifold for example
