Calver Special Tuning has the capability to do all cylinder head work from simply fitting unleaded fuel friendly exhaust valve seat inserts, through straight forward reconditioning to full race specification. A no expense spared approach to equipment to produce the very best results means Calver Special Tuning uses high-precision machinery manufactured in Switzerland to the highest standards. MIRA for valve seat cutting machinery and tooling, and Suhner machines and tooling for modifying/grinding duties.
Having started racing in Mini Miglias in 1978, the desire for knowledge pushed me in to doing all my own research, investing steadily over the years in equipment to assist me in that endeavour. Culminating in purchasing flow benches to aid development and achieve repeatable consistency.
Racing a Mini naturally lead me in to specialising in all things A-series, but in more recent years I have applied my knowledge to heads for other engines. MGB, MG XPAG, MG T type, MGC, Healey 3.0 litre, Triumph TR4, Volvo B18, Alvis and more recently still several multi-valve twin cam modern engine heads.
