Leading A-Series engine specialist since 1981
Standard size high quality bronze valve guide set for 1275 cylinder heads, to suit MED 9/32" stem valves.
The guides are precision machined in the UK and are by far the best quality on the market, as used in all MED fast road and race heads.
There are differing tapers for the inlet and exhaust guides to maximise air flow.
All valve guides need to be reamed once fitted to give the correct valve stem clearance. Please contact us for recommendations if you're unsure on sizing.
