I think the valve cut outs are bigger to match the bigger inlet valves & higher lift cams, in any case it was a job lot for £150.00, it would no doubt cost £40/£50 to get the pistons machined so esier to use the 02 ones. Big bore! I wish, this is an economy tune.
i can understand that...good price for the bits..:thumbup...
i dont really want to get into tearing the engine down so sticking with bolt on bits..exhaust,airbox etc
i've got some 57's sitting here waiting to go on:devious
