Valve Guide 1200-1600cc 8mm 3rd Oversize - All Questions

Afternoon Dave,

Sorry no these are meant for a 1600 Typ1 head.

Oversize refers to the outer diameter of the guide, 3rd oversize on a Typ1 motor is 12.26mm.

But for your motor unless the guide is loose in the head then go for a stock sized one.

Part numbers - 021-101-403/A & 021-101-417/A.

Don't worry about the crimp, the proper way to remove guides is to first drill the guide with a coring drill approx 1mm smaller than the o/d of the guide, go down approx 3/4 of the length of the guide from the chamber side then knock them out towards the spring side of the guide. Be careful here and centre the drill bit in a prill press, not a hand held drill, you don't want to break through the guide and start drilling the head.
