JeffR Posted September 22, 2011 Author Share Posted September 22, 2011 thats that solved then. Now comes the fun part of trying to do the job with the heads in situ Quote Link to comment Share on other sites More sharing options...
rusty_wingnut Posted September 23, 2011 Share Posted September 23, 2011 Has anyone ever converted these bolts to studs? Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted September 23, 2011 Share Posted September 23, 2011 Yes - and there's a company (I think it's Namrick) who sell special studs which have a finer thread on the "outside" end and proper brass nuts. Got a set waiting to go on the 109 in fact. Quote Link to comment Share on other sites More sharing options...
rusty_wingnut Posted September 23, 2011 Share Posted September 23, 2011 seems like a sensible thing to do IMO, less risky for sure. Cheers for the info. Quote Link to comment Share on other sites More sharing options...
JeffR Posted September 24, 2011 Author Share Posted September 24, 2011 try these http://www.ebay.co.uk/itm/Land-Rover-V8-Cast-Iron-Ex-Mnfd-STAINLESS-STUDS-NUTS-/220619265248?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item335deed4e0. Look like a very good idea. They also do em for tubular manifolds Quote Link to comment Share on other sites More sharing options...
