The valve springs in this section suit the Holden 186 and 202 striaght six engines.

These valve springs have been categorised by their ability to be fitted to your engine without any special machining of the valve spring seat or valve guide. Of course this is dependant on total lift at the valve and you still need to check for coil bind and retainer to valve guide stem clearance to ensure you do not break parts.

Note that most standard valve spring retainers are not that flash and we highly recommend purchasing the recommended valve spring retainer and collets.
