Datsun Roadster Racing

Well, I received a notice about your post so I guess it's still breathing. We just need people to post questions, answers etc. to get it rolling again. I think the 3ll forum site has mostly replaced the traffic here.

Good Luck Bill!

Last weekend was my first race in the ex-Bob Sharp, ex-Dick Tillinger, 1967 Datsun 2000. It was fun to be racing a roadster again as I've been racing a 240Z quite a bit the past 10 years.

You can do that. Dean used to sell some retainers that would fit. I've also seen valves turned down to 8mm just on the ends to use L-series hardware. You'll need to machine the keeper groove as well. Next rebuild have the 8mm stem valves made and replace the guides. Less weight, better flow and easi...

Ron,
Your best bet is to have some valves made with 8mm stems then you can use L-series retainers, keepers and lash pads. This is the best fix IMO.
