TR4A type iron cylinder head. Fully machined bare head fitted with core plugs and pushrod tubes. No value guides fitted. This head is ideal for those who want to have the head completed to their own specification with bronze guides and whatever seats are required to suit your specified valves.
Please be aware that the shroud over the inlet valves, which is usually removed when a cylinder head is 'worked' has been omitted on these heads. This modification provides a great improvement in gas flow but does require the use of a solid copper gasket to ensure a reliable gas tight seal. RevingtonTR sell a range of suitable gaskets, the thickness of which can be chosen to provide a desired compression ratio. Please see the list below.
An aluminium version of this head, 511695AX is available as are 511695NF
and 511695ANF which are the same head with core plugs and pushrod tubes missing, which need to be purchased separately.
