I would avoid the stainless steel. Whilst they sound like a great solution, they are a complete nightmare to remove, if they strip threads or need removing.
Go for original bolts from Porsche and monitor condition every few years with view to replace. Ensure new gaskets and properly torqued.
Another option is titanium at a price http://www.porschetistuds.co.uk/ The hardest part is removing old bolts - mine had to drilled out and threads realigned. Not replaced my manifold yet, but read some aftermarket reduce clearance too, so check.

guys thanks for input, shall take a closer look at manifolds, there is little room to start with so shall watch out for reduced clearance. also will go with porsche bolts and gaskets and monitor every oil change, again if anybody spots manifolds or has any experience with german company please let me know, i have got my hands on a stomski jig so hope it will ease the pain, regards Elwyn

I changed mine for a multiple branch type of eBay great quality just use porsche gaskets. Studs etc mine were terrible but I used a mini conductor on them to heat them red hot but with no flame. They all came out with ease I put back steel ones from Design 911. If you can give each bolt a single hard hit to the top first. Have fun
thanks again folks, shall keep looking for manifolds, if its anything like the fun i had with brake fluid change, spent evenings heating and cooling nipples, last one snapped, only for friend with machine shop would have been new caliper, shall be very careful, plan sometime september, Elwyn
