while considering selling my dart pro 1 heads and getting some street legal AFR 180cc I noticed that my rockerarms were rubbing on the retainer.
the engine builders installed the rocker arms ,picked the pushrods and installed the heads on my block.
actually made small indents on the underside of the rocker arm.
so I have bought some lash caps and ground down to fit with my locks that are not recessed for lash caps.
this created enough clearance for them not to touch.
I bought the heads off an online store on ebay and I think the guy used 7 degree locks with 10 degree retainers.
the top of lock sits down between an 1/8 and 3/16 inside the retainer. so far in all valvetrain pictures I can find the lock
sits either flush or a hair above the opening in the retainer.
don't know what valve springs he used other than comp cams dual valve springs with dampner. i have measured them roughly with a tape measure and they are either the 1.437, 1.460, or 1.464. question is the installed height and seat load at installed height.
installed at roughly 1.9 which would be correct for the 1.464.
this sucks. maybe i expect too much but considering the place that built my engine builds race engines
and as they put have built 20,000 dollar engines you would think they would have noticed that the lock was sitting too deep
in the retainer and mentioned that i needed to have that fixed. would also think they would have properly checked the clearance on
the rockerarm to retainer.
