OK Carl or Stew heres one for you boyz !
R&D valve springs are about 20m.m. longer than Std ones -yeh- 20m.m.!!! have you had any issues with spring coil bounding on full lift when using the cam I,m getting that Carl recommended, a Waggetts 738 in conjuction with a Wiscoe 10:1 any clearance issues with valve to piston clearance on full valve lift, I believe .060 thou will do there (correct ? )
Also I,ve bought R&D Bronze guides (I know the cast ones are better but 3 times the price ) so the problem is on the R&D guides there is only a 1m.m. shoulder to act as a stop/ flange when the guides are fully driven home , therefor there is not enough of a flange / lip to have an O ring under that face to stop oil finding its way past the outside of the guide. I can machine a small under cut groove tight in the corner below the 1m.m. shoulder to retain an O ring but I thought I,d ask before doing it to see if anyone has a better fix ? Thanks guys. Lee
