Cylinder heads on a MY2001, 2.5l converstion
Hi ,
Can anyone advise in the best heads to use when converting a classic MY2001 to a 2.5l bottom end/short block,
Are the standard UK ones good enough or is it better to get them reworked or get hold of some STi ones ??

The cams are different i.e. wilder with better breathing

Valves are different but same size I believe, solid followers, stronger springs and higher lift cams. The JDM have wider inlet tracts on >STi7 also I think
