I run a tight lash (.014/.016) Bullet Solid Roller and it isn't too bad. It's a little over .700 lift and I use the .815 wheel Bam lifters with the pressure fed axles and so far so good. I don't have a ton of miles on it yet though so time will tell.
.700" Lift is probably not a Roller Cam Profile designed for extended
Street driving usage ?
IMO....
If it calls for/requires 225+ Lbs Seat/Closed V/Spring pressure and 550 # V/Spring rates then high probability it's not "if" but rather "when" a V/Spring(s) begin to decline or go away under the rigors of continued street driving.... wherein when that happens it doesn't matter "what" or how good Parts were used.... things don't stay where they are supposed to and they crash together and break.
just say'in... "IMO"
if you are running those "as mentioned' above V/Spring specs on the street ? (225# closed and 550 # rate),
you are well advised to be vigilante in checking your V/Spring Pressures/Rates frequently.... and NEVER put any rpm to the engine for the first 15-20 minutes of operation from a Cold start, until the V/Springs have had a good chance to warm up/Thermally stabilize....
remember...
just because the Temp gauge comes up ?
The V/Springs are still dead nuts COLD because the only way they warm up is by conducting heat off the Head or warm Oil flowing over them.... and cycling those V/Springs alloys cold is a sure fire recipe for rapid tension decline then precipitating V/Train inconsistencies(breakage)
STREET Mechanical Roller Cam Profiles.... designed for extended
STREET usage.... typically only require 160-175# closed V/Spring Pressures and 425-450# V/Spring rates....only slightly more than HR Cams..... but
more importantly....
that is because the speeds/rates of Valve opening is maintained low enough to prevent V/Spring alloy fatigue across a far wider thermal range of operating temps ?
