Mike The exhaust manifold on my Sp20 SC had multiple cracks a few years ago - It was repaired by Dave Baker at Technilock in Swadlincote Derbys - <!-- m --><a class="postlink" href="http://www.cast-iron-repair.com">http://www.cast-iron-repair.com</a><!-- m --> - Since then the car has done 17,000 from the North of Norway all the way down to the Med including multiple Alpine, Picos and Pyrenean passes over 2,500 meters and regular 70mph+ blasts up and down the M1 with no recurrence of the crack. The repairs were a mixture of welding and stitching. Dave's quality is excellent - he does work for P&A Wood and a few of the European specialists. However he is a one man band and organisation isn't his forte - He's done 2 other jobs for me as well - one great, one where he messed me around for months and I ended up pulling the work because he was swamped and wouldn't face up to it- overall score 2 great, 1 poor. Be prepared to listen to his life story though! There are a few other metal stitchers and cast iron welders in the area (S Derbyshire/ NW Leics) who all learnt their trade at British Steel and the specialist foundry's that used to be here and have set up on their own - however I haven't used any of the others so no comment on quality or attitude.
