decided to try the 8/07 and found some interesting stuff, had to clearance the head on the exhaust side for the lobes to clear the casting, just touching the head casting on the intake lobe actually ! and the exhaust lobe was way to close for comfort......
Couple of minutes with the porting tool fixed that easy enough, pics to follow
clearance from the valve spring edge to the rocker arms is real tight also, any of you you guys notice this with 8/07 installs ? using the dual KW spring set. Doesn't touch but not allot of clearance, anyone actually putting a bit of a clearance radius on the rocker arms ? Rather not touch them but will get in there with some feeler gauges to check.....
seems strange since I'm coming off a Thumper stage 5 which is supposed to be more aggressive, maybe a different - smaller base circle
I never really noticed but maybe it was running real close.....
seems my exhaust rocker swivel feet are not great either having a hell of jobs getting the clearances set right........ cupped after 35hrs of heavy use ?? could be I guess......
going to try the 1/6 turn adjustment method
