MGB 1800 stage 2 gas flowed cylinder head suitable for 18V engines (1971-80). Original 12H2709 big valve head, polish and ported, new guides, professionally reconditioned and machined by Headline MK Ltd in 2018. This cylinder head was recently removed from my own car as I have changed the engine for a V8, last photo shows cylinder head before fitment. The head gives a significant improvement in performance, it has covered less then 3000 miles and is in full working order, any inspection welcome. Valve seats are as original, you may want to fit unleaded valve seats if you intend to cover high mileage. If you require more information then please…
