Rock arm clerance
 

Hey all,

I am re-assembling my 383 and decided to upgrade my rocker shaft hold downs to the Mancini racing blue anodized blocks. Not sure there is really any gain but it looks cool lol.

when I try to put them on with my roller rockers, everything was too tight to even bolt it all on. The guys at Mancini said to shave a bit off the sides to make them fit. Online I have seen between 15 and 30 thousandths clerance for each pair of rockers. What is correct?

thanks everyone!

0.030 is what I remember..
