Re: Roller Rockers and Tappet Noise

[Daniel1312@aol.com]

I have to say that I remain unconvinced that Pierce know much about anything 
when it comes to performance tuning.  In any event there is a full 
explanation in David Vizards book (page 306 of the first yellow edition) that 
explains why hi-lift rockers need more clearance.  YES, I know you can play 
around with clearances with the time, inclination and money to spend on the 
dyno which I haven't done but guess that DV has.

So, unless I hear different it's another black mark against Pierce.
