Late Style Valve Guide – M10/M30



Valve Stem Size * 

Product Description

Late style Valve Guides for your M10 or M30 cylinder head. The late style guides allow you to run dual valve springs (but are still compatible with single springs) and the late style Valve Stem Seals which use a nice Viton seal (see related listing). These are ideal for any cylinder head rebuild.

Our valve guides are made to exceed all OEM specs, right here in the USA. The Manganese-bronze alloy used features the highest heat transfer rate of any bronze valve guide alloy.

Important Your machinist must specify the proper size needed, do not assume you need the standard size.

M10 has 8 guides. M30 has 12.
