Thanks guys, I was hoping to get informtion as to Mountunes recommendation as to valve spring requirements (double, single etc) , lifter type (solid or hydraulic) and which is exhaust or inlet. Are they 4wd with spacer or 2wd cams and anything else I would need to know. They are brand new bar 2 hours on a dyno, and they came with a head but the seller couldnt find the details.
Ill keep hoping here and ringing mountune until they answer me.

cheers,
Justin P
