go to comiskey engineering in Portadown, Mahon road. Or I use an independent guy in Scotch Street who is well regarded in bike racing circles. His name is Ciaran Macaloran
Sorry to revive this old thread but I'm gonna need my Rover V8 heads skimmed by 0.5mm to allow the use of a composite gasket. How much does this cost? And do you have any contact details for the guy in Scotch Street?
