MKIV CYLINDER BLOCK IDENTIFICATION
Recessed or Non-Recessed Cylinder Bores?
EARLY MkIV engines (to engine number FH25000E) have (as all previous
Spitfires) Non-Recessed cylinder bores, and use a plain head gasket.
LATE MkIV (from engine number FH25001E), and ALL 1500 engines have a
Recessed Lip at the top of the cylinder bores adjacent to the block
face, necessitating a particular type of head gasket, which can be
identified by a small 'Tag' that stands proud at the rear of the block.
This kit contains everything you need to recondition your short engine. We assume you will have the block re-bored and any other machining done as required.
IMPORTANT - Pistons are supplied +0.020" oversize. Bearing sets are supplied in standard size. Please advise specific sizes required at time of ordering.
