My question is what for springs to use for cams with slightly higher lift (1mm) are the TRD/HKS.... cams not too stiff? Its enought to buy only new stock springs? Catcams, kelford recomend stock springs for the stage1,2 cams.

OEM spring have there limit@ about 9mm (some say 8.5) but personaly I wouldn't trust 25year old springs being at their limit on a performance engine... the HKS will deal with 9mm easily and wont be overkill (HKS cams are less than 8.5 anyway)
